Ze is a neopronoun proposed for use as a singular, gender-neutral personal pronoun in English, functioning as a substitute for the sexed pronouns "he" or "she" in reference to individuals.[1] First attested in print in 1864 by an anonymous writer identified as J. W. L., who introduced "ze" alongside possessive and reflexive forms like "hizer" to address the absence of a dedicated neutral singular pronoun in the language, distinct from the plural "they."[2] Common contemporary variants include the sets "ze/hir/hirs" or "ze/zir/zirs," with the latter adapting spellings to evoke a more phonetic neutrality while drawing from earlier 19th-century experiments in pronounreform.[3]Despite recurring proposals over more than 150 years—spanning feminist linguistic advocacy in the 1800s and later non-binary identity movements—"ze" has achieved negligible penetration in everyday English usage, overshadowed by the established singular "they," which traces to at least the 14th century and requires no novel vocabulary.[3] Empirical indicators of rarity include its absence from major dictionaries until recent niche inclusions and minimal occurrence in corpora compared to "they/them," reflecting practical barriers such as phonetic unfamiliarity and cognitive load on speakers.[2] Institutional pushes for adoption, such as a 2015 University of Tennessee advisory urging faculty to default to "ze/zir" in uncertain cases, provoked significant backlash, leading to the guidance's withdrawal amid claims of overreach into compelled speech and disruption of pedagogical clarity.[4] Similar efforts in classrooms have been critiqued for substituting invented forms over functional alternatives, potentially confusing learners without commensurate benefits in communication precision.[5]
Linguistics and language
Gender-neutral pronouns
"Ze" functions as a nominative singular gender-neutral pronoun in English, serving as an alternative to the sex-distinguishing "he" or "she." It pairs with object and possessive forms such as "hir" (object/possessive) or "zir" (possessive variant), yielding paradigms like ze/hir or ze/zir.[6][7] These neopronouns emerged to reference individuals without specifying biological sex, primarily advocated by proponents of non-binary gender identities since the late 20th century.[8]Proposals for "ze" predate modern usage, with an early documented suggestion in 1864 by an anonymous writer identified as J.W.L., amid 19th-century efforts to invent neutral terms for generic references.[2] The form saw revival in the 1970s, entering linguistic discussions around gender-neutral language, though dictionaries first tracked it systematically from 1972.[2] A notable literary adoption occurred in 1996, when author Kate Bornstein used "ze/hir" for a character in her novel Nearly Roadkill, marking one of the earliest prominent fictional applications.[2] Derived partly from earlier variants like "sie/hir" to reduce perceived femininity, "ze" gained entry into major references like the Oxford English Dictionary by 2018, reflecting niche but persistent advocacy.[9][2]Despite these developments, "ze" exhibits limited empirical adoption in everyday English, overshadowed by the singular "they," which traces to 14th-century texts like the poem William the Werewolf and aligns with natural linguistic evolution rather than deliberate invention.[10] Linguistic research indicates "ze" is interpreted as gender-neutral in controlled settings but faces barriers in comprehension and habitual use due to its novelty and deviation from established morphology.[7] Usage persists in specific activist, academic, and online communities promoting expanded pronoun options, yet surveys and corpora show it comprising a fractional share of neutral references compared to "they."[3] Proponents argue it addresses perceived gaps in binary pronouns, while critics highlight redundancy given "they's" historical and functional adequacy.[11]
Other linguistic uses
In Japanese, ze (ぜ) functions as an informal sentence-final particle, typically employed by males to add emphasis, assertiveness, or a hortative tone, urging action or reminding the listener of something expected to be known.[12] It conveys one-sided subjective claims with a rough, brash nuance, differing from the related particle zo (ぞ), which lacks the confirmatory or advisory function of ze.[12] Examples include exhortations like "Ikō ze!" ("Let's go!"), where it pushes the addressee toward compliance in casual speech.[13]In Hebrew, ze (זֶה) serves as a demonstrativepronoun meaning "this," often co-occurring with sentential subjects to indicate proximity or specificity in syntax.[14] It exhibits flexible positioning, appearing sentence-initially or -finally while maintaining agreement with antecedents, as analyzed in syntactic studies of Modern Hebrew.[14]In Russian, ze acts as a discourse marker to access "hearer-old" information, signaling that the speaker assumes the addressee possesses prior knowledge of the referenced content, thereby structuring conversational presuppositions.[15]In Slavic languages such as Polish and Czech, ze appears as a variant preposition derived from Proto-Slavic jьz, denoting "from," "of," or "with" in genitive contexts, particularly after certain consonants to ease pronunciation (e.g., Polish "ze Słonska" indicating origin).[16]
People
Stage names and pseudonyms
Tom Zé serves as the professional pseudonym for Antônio José Santana Martins, a Brazilian singer-songwriter born in 1936 in Irará, Bahia. Derived from the Portuguese diminutive "Zé" for José—echoing his middle name—the moniker reflects informal Brazilian naming conventions while encapsulating his avant-garde, tropicália-influenced style, which blends samba, experimental sounds, and social commentary. Martins adopted this name early in his career, releasing innovative albums in the 1970s that critiqued urbanization and consumerism before achieving international acclaim via David Byrne's 1990 reissues on Luaka Bop.[17][18]Swedish-Polish rapper Jozef Wojciechowicz performs under the stage name Z.E (stylized as ZE or z.e), originating from Tensta, a suburb of Stockholm. Born in 1994, he emerged in the Swedish hip-hop scene, achieving platinum certification for tracks blending trap influences with multilingual lyrics in Swedish, Polish, and English. His pseudonym emphasizes brevity and urban edge, aligning with his breakout singles and acting roles in Swedish media.[19][20]Circus performer and former broadcast journalist John Andrew Lepiarz employs the pseudonym Jacques Ze Whipper for his bullwhip artistry, adopting a theatrical French persona complete with accent and mustache to heighten comedic and skillful displays. Developed during his transition from NPR affiliate reporting to full-time performance around 2023, the name evokes whimsical, vaudeville flair while facilitating viral TikTok content and live shows cracking whips at speeds up to 700 mph.[21][22][23]
Given names
Ze is a rare given name, primarily used in informal or diminutive contexts rather than as a formal standalone name in most cultures. In Portuguese-speaking regions, "Zé" (frequently anglicized or simplified to "Ze" in non-accented writing) serves as a common nickname for José, derived from the Hebrew Yosef meaning "he will add," and is bestowed upon individuals at birth or informally later in life.[24] This usage reflects a tradition of affectionate shortenings in Iberian naming practices, where it appears in records dating back centuries but lacks widespread adoption as a primary given name outside Brazil and Portugal.[24]In Chinese contexts, Ze (澤 or similar characters) can function as a given name component, connoting "pond," "marsh," or "grace," symbolizing tranquility or benevolence, though it more commonly appears as a surname or in compound names.[25] Standalone usage remains uncommon globally, with no dominant etymological root in Western traditions; speculative user-submitted meanings, such as religious interpretations like "Jesus loves you," lack verifiable historical basis and stem from modern personal attributions rather than linguistic evidence.[26]Popularity data from the United States Social Security Administration indicates Ze first entered records in 1999, peaking at rank 1,291 that year with fewer than 200 occurrences annually thereafter, reflecting its niche appeal possibly as a gender-neutral or minimalist choice amid trends toward short, unconventional names.[27] By the 2020s, it ranked below 35,000 in boy name lists, underscoring its obscurity compared to established names starting with Z.[25] Notable bearers include American multimedia artist Hosea Jan "Ze" Frank (born 1971), who adopted the mononym professionally, highlighting its potential in creative or performative identities. No large-scale demographic studies confirm gender preferences, but records skew male, aligning with diminutive origins from masculine names like José.
Surnames
The surname Ze is held by approximately 35,989 people globally, with the highest incidence in Cameroon, where it accounts for over 25,000 bearers and exhibits the greatest density.[28][29] About 90% of occurrences are in Africa, concentrated in Central Africa (73%) and specifically Central Bantu Africa (52%), reflecting regional ethnic and linguistic patterns among Bantu-speaking populations.[28]In Chinese contexts, Ze (often 泽 or 迮) traces to rare surnames with meanings related to "marsh," "grace," or "river," and historical migrations from provinces like Guangdong and Fujian account for overseas bearers in the past four centuries.[30][31] One variant links to the ancient figure Xi He (羲和), associating it with the surname 和 ("peace") in Mandarin transliteration, though this form remains uncommon outside specific lineages.[32]The accented variant Zé, prevalent in Portuguese-influenced regions, appears mostly in Southern Africa (79% of cases), particularly Luso-Southern Africa such as Angola and Mozambique, where it derives from the diminutive of José and has been adopted as a hereditary surname in colonial and post-colonial censuses.[33][34] In the United States, early 20th-century records show clusters in New York, linked to immigrant waves, but overall numbers remain low compared to African concentrations.[35]No widely prominent historical or contemporary figures bear the exact surname Ze, though genealogical databases like FamilySearch document over 500,000 associated records spanning birth, death, and census data across these regions.[32] Variants like Ze'evi exist in Ashkenazi Jewish contexts but differ etymologically.
Zeze is a historical district in Ōtsu, Shiga Prefecture, Japan, known for the ruins of Zeze Castle, constructed in 1601 by Toda Katsushige as a branch of Sawayama Castle.[36] The site, now Zeze Castle Ruins Park, features remnants of the castle's stone walls and moats, and serves as a popular cherry blossom viewing spot in spring.[37]In Iraq's Kurdistan Region, Zêwe is a locality in Ranya District, Sulaymaniyah Governorate, situated at an elevation of 1,094 meters near the Iranian border, characterized by mountainous terrain typical of the Zagros range.[38] Similarly, Zewa is a village in Amedi District, Dohuk Governorate, located in northern Iraq's rugged landscape.[39]In China, Ze Zhu Lin Cun is a village in the country, documented in geographic mapping resources.[40] Additionally, Laxiwa (Lasêwa) Town in Guide County, Qinghai Province, incorporates "ze" in its Tibetan name (la ze ba grong rdal), reflecting local ethnic nomenclature in the Tibetan Plateau region. These minor settlements highlight "Ze" as a toponymic element in Asian place names, often linked to local languages or historical clans.
Other geographical features
Ze'aken Shet' is an intermittent stream in central Ethiopia, part of the country's diverse hydrological network characterized by seasonal water flows dependent on rainfall patterns in the highlands.[41] Similarly, Ze`ilan Wenz represents another intermittent stream in the region, contributing to local erosion and sediment transport processes typical of Ethiopia's semi-arid to sub-humid landscapes.[41] These minor watercourses are documented in geographical gazetteers but lack significant prominence in broader hydrological studies compared to major rivers. No large-scale mountains, lakes, or other prominent landforms exclusively named "Ze" are recorded outside Asian contexts.
Science and mathematics
Physical sciences
In atomic physics, Ze denotes the magnitude of the electric charge of an atomic nucleus, where Z is the atomic number (the number of protons in the nucleus) and e is the elementary charge, approximately $1.602 \times 10^{-19} coulombs.[42] Each proton carries a charge of +e, so the total nuclear charge is +Ze, which exerts a Coulomb attraction on the negatively charged electrons orbiting the nucleus. This notation is central to early atomic models, including Ernest Rutherford's 1911 planetary model, where the nuclear charge Ze balances the centrifugal force on electrons, and Niels Bohr's 1913 quantized model, which incorporates Ze in the expression for orbital energy levels: E_n = -\frac{(Ze)^2}{8 \epsilon_0^2 h^2 n^2} m_e, with m_e as electron mass, \epsilon_0 as vacuum permittivity, h as Planck's constant, and n as the principal quantum number.The concept underscores the scaling of nuclear attraction with atomic number; for hydrogen (Z=1), Ze = e, while for heavier elements like uranium (Z=92), Ze reaches 92e, influencing electron binding energies and ionization potentials. In quantum mechanical treatments, such as the Schrödinger equation for hydrogen-like atoms, the potential term is -Ze^2 / (4\pi \epsilon_0 r), confirming the foundational role of Ze in describing atomic structure and spectra. Experimental verification comes from scattering experiments, like Rutherford's 1909 alpha-particle gold foil tests, which inferred nuclear charge proportional to Z via deflection angles consistent with Coulomb repulsion from Ze.
Biological and chemical terms
Zeatin is a cytokinin-type plant hormone derived from adenine, existing in cis- and trans-isomers, that promotes cell division, shoot formation, and delays senescence in plants.[43] Discovered in 1963 from immature corn kernels (Zea mays), it was the first naturally occurring cytokinin identified, extracted from the endosperm where concentrations reach up to 60 μg/g fresh weight.[44] Chemically, zeatin features a purine ring with a prenyl side chain containing hydroxyl, amino, and olefin groups, enabling its role in regulating meristematic growth and stress responses via adenine receptors.[43] In biochemical applications, trans-zeatin induces adventitious shoot formation in tissue culture at concentrations of 1–5 μM.[45]Zein constitutes 45–50% of maize endosperm proteins, classified as a prolamin storage protein soluble in 70–80% ethanol due to its high hydrophobicity from neutral and hydrophobic amino acids like leucine (up to 20%) and proline.[46] Encoded by multigene families on chromosomes 4 and 7, zein forms protein bodies within endoplasmic reticulum-derived organelles during seed development, peaking at 20–30 days post-pollination when it accounts for 70% of total seed protein.[47] Variants include α-zein (19–22 kDa, 70–80% of total), β-zein (14–15 kDa), γ-zein (27–28 kDa), and δ-zein (10 kDa), with α-zein featuring repetitive sequences that limit nutritional value due to low lysine (1–2%) and tryptophan.[48] Biotechnologically, zein serves as a biodegradable biopolymer for coatings and nanoparticles, leveraging its film-forming properties without cross-linking agents.[49]Zollinger-Ellison syndrome (ZES) is a rare gastrin-secreting neuroendocrine tumor disorder, with incidence of 0.1–1 per million annually, causing hypergastrinemia and resultant gastric acid hypersecretion exceeding 100 mEq/h in 60% of cases.[50] Gastrinomas, typically 90% malignant and located in the gastrinoma triangle (duodenum 50–70%, pancreas 20–40%), elevate fasting serum gastrin levels above 1000 pg/mL in 85% of patients, leading to refractory peptic ulcers in 90–95% and diarrhea from acid inactivation of pancreatic enzymes.[51] Diagnosis involves secretin stimulation testing, where paradoxical gastrin rise >200 pg/mL confirms ZES, alongside endoscopic biopsy and imaging like somatostatin receptor scintigraphy detecting 80–90% of tumors.[52] Up to 25% of sporadic cases and 20–25% of familial ZES associate with multiple endocrine neoplasia type 1 (MEN1), involving MEN1 gene mutations on chromosome 11q13.[53] Treatment combines proton pump inhibitors (e.g., omeprazole 40–120 mg/day) for acid control and surgical resection for localized tumors, achieving 5-year survival of 60–90% for duodenal versus <20% for metastatic disease.[54]
Arts, mythology, and fiction
Mythological and historical figures
Bai Ze (白泽), also known as the "white marsh" or "white zebra" in literal translation, is a benevolent mythical creature in ancient Chinese lore, revered for its encyclopedic knowledge of the spirit world. Legends describe it appearing to the Yellow Emperor (Huangdi), a semi-mythical ruler circa 2697–2597 BCE, during his eastern tour, where it revealed the names, forms, and methods to subdue 11,520 varieties of ghosts, demons, and deities. This encounter purportedly enlightened the emperor on governance, exorcism, and harmony between human and supernatural realms, with the knowledge documented in the now-lost Bái Zé Tú (Illustrated Treatise on Bai Ze).[55][56]Depictions portray Bai Ze as an auspicious, chimeric beast resembling a white ox or cow with cloven hooves, a single horn or goat-like horns, a lion's mane, and occasionally multiple eyes—typically six on its flanks and nine on its head—enabling omniscient perception. It possesses the ability to speak human languages fluently, embodying wisdom, prophecy, and protective power against malevolent forces. In Chinese cosmology, its manifestation signals prosperity and imperial virtue, serving as a divine advisor that bridges mortal rulers and ethereal entities.[57][56]The creature's lore influenced East Asian traditions, evolving into the Japanese Hakutaku by the Tang Dynasty (618–907 CE), where it retained attributes of foresight and guardianship but adapted to local Shinto-Buddhist syncretism. Archaeological and artistic evidence, such as Han Dynasty (206 BCE–220 CE) motifs and later imperial seals, underscores Bai Ze's role as a symbol of enlightened rule and cosmic order, though textual accounts remain fragmentary due to historical losses like book burnings in 213 BCE. No verifiable historical human figures bear the exact name "Ze" with significant documented impact, though variants like Ze'ev appear in modern contexts unrelated to ancient personages.[58][55]
Fictional characters and works
Zé Carioca serves as the Brazilian Portuguese moniker for José Carioca, an anthropomorphic parrot character created by The Walt Disney Company and debuting in the 1943 animated feature Saludos Amigos.[59] Developed during Walt Disney's 1941 goodwill tour of South America to counter Nazi influence, the character draws from Brazilian malandro archetypes, portraying a suave, samba-loving resident of Rio de Janeiro who frequently interacts with Donald Duck in subsequent shorts and comics.[60] Zé Carioca has appeared in over 20 Disney comics series in Brazil since the 1950s, often as a protagonist in stories set in the fictional Vila Xurupita neighborhood.In the 2002 Brazilian crime drama film City of God, directed by Fernando Meirelles and Kátia Lund, Li'l Zé (also known as Zé Pequeno) emerges as the central antagonist, a sociopathic drug trafficker who ascends from child criminal to dominant figure in Rio de Janeiro's Cidade de Deus favela between 1968 and 1980. Portrayed by Leandro Firmino, the character orchestrates territorial wars, enforces brutal control through violence, and embodies the cycle of poverty-driven crime, with his arc culminating in a hail of bullets during a revenge standoff.[61] Adapted from Paulo Lins's 1997 novel of the same name, Li'l Zé draws loose inspiration from real favela kingpins like Wallace Oliveira, though the film fictionalizes events for narrative impact.[62]Xue Ze appears as a minor fictional officer in the Wei kingdom within Luo Guanzhong's 14th-century historical novel Romance of the Three Kingdoms, where he leads an ambush against Shu Han envoy Deng Zhi on orders from Xiahou Mao but is promptly killed by the warrior Zhang Bao during the engagement.[63] This brief role underscores the novel's dramatized depictions of Three Kingdoms-era skirmishes, absent from primary historical records like the Records of the Three Kingdoms.[64]
Artistic and media references
In music, ZE Records, founded in New York in 1978 by Michael Zilkha and Michel Esteban, became influential in the no-wave and mutant disco genres, releasing works by artists such as James White and the Blacks and Kid Creole & the Coconuts that blended punk, funk, and electronic elements.[65][66]In film, Li'l Zé (Zé Pequeno) serves as the central antagonist in the 2002 Brazilian drama City of God, depicted as an ambitious and violent youth who ascends to control the drug trade in Rio de Janeiro's favelas, portrayed by Leandro Firmino.[61][62]In television animation, the Te Xuan Ze is the guardian role assumed by protagonist Juniper Lee in The Life and Times of Juniper Lee, a Cartoon Network series airing from 2005 to 2007, where she mediates conflicts between human and magical realms while managing adolescent life.[67][68]In traditional Chinese art, Bai Ze (White Ze), a mythical beast from ancient texts like the Shanhaijing, is commonly illustrated in paintings and door hangings as a wise, multi-eyed creature symbolizing supernatural knowledge and protection against evil spirits.[57][69]Hosea Jan "Ze" Frank, an American digital media creator, has produced viral web series including the show with zefrank (2006–2007) and the ongoing True Facts educational humor videos on YouTube, amassing millions of views through narrated animal behaviors and interactive online performance art.[70][71]
Transportation and engineering
Vehicles and models
Renault's Z.E. designation, standing for Zero Emission, denotes a lineup of battery-electric vehicles introduced as part of the company's commitment to electric mobility starting in 2009.[72] The initiative began with concept vehicles showcased at motor shows, evolving into production models aimed at urban and commercial use, with over 500,000 units sold in Europe by 2019.[72]Key passenger models include the Zoe, a compact hatchback launched in 2012 with initial battery capacities of 22 kWh, later upgraded to 52 kWh in the Z.E. 50 variant by 2019, offering ranges up to 395 km under WLTP testing.[73] Commercial variants encompass the Kangoo Z.E. van, available since 2011 with a 44 kWh battery in later iterations providing 270 km range, and the Master Z.E. introduced in 2010 for light-duty transport, expanded to 3.5-tonne gross vehicle weight options by 2020.[74][73]Other models in the Z.E. family feature the Fluence Z.E. sedan, produced from 2011 with a 70 km range on its 22 kWh battery, targeted at fleet operators, and the K-ZE, a budget city car unveiled in 2018 with a 26.8 kWh pack yielding 270 km NEDC range, later rebadged as the Dacia Spring.[75] The Twingo Z.E., announced in 2020, utilizes an 18 kWh battery and rear-mounted 60 kW motor for urban agility, with production limited to approximately 500 units annually.[76]
These models emphasize affordability and practicality, with Renault achieving a 22.2% European electric vehicle market share in 2018 through innovations like the Caméléon charger for bidirectional energy flow.[72] Independent testing has validated ranges under real-world conditions, though early models faced limitations from battery leasing programs to mitigate high upfront costs.[75]
Infrastructure and systems
Zero-emission (ZE) infrastructure systems encompass charging stations, hydrogen refueling facilities, and corridor networks designed to support battery-electric and fuel-cell electric vehicles, particularly in freight and heavy-duty transportation. These systems address the electrification of transport by providing reliable power access, with deployment guided by national strategies such as the U.S. National Zero-Emission Freight Corridor Strategy, released on March 12, 2024, which targets scalable ZE medium- and heavy-duty vehicle (ZE-MHDV) infrastructure along the National Highway Freight Network to facilitate 30% ZE-MHDV sales by 2030 and 100% by 2040.[77][78]In Canada, the Zero Emission Vehicle Infrastructure Program (ZEVIP), administered by Natural Resources Canada since 2019, funds public EV chargers and hydrogen stations, with over $680 million allocated by 2024 to deploy more than 10,000 charging ports and 40 hydrogen refueling stations across provinces, prioritizing high-traffic corridors and urban areas to reduce range anxiety and enable fleet transitions.[79] The program's emphasis on fast-charging (up to 350 kW) and megawatt-level capabilities supports heavy-duty applications, though deployment lags behind light-duty EV infrastructure due to higher power demands and grid integration challenges.[79]Projections from the International Council on Clean Transportation indicate that by 2030, the U.S. will require approximately 200,000 public charging ports for ZE-MHDVs, concentrated in freight-heavy states like California and Texas, with needs doubling by 2035 to accommodate growing adoption amid economic barriers like upfront costs exceeding $500 per kW for depot chargers.[80] Complementary tools, such as the National Zero-Emission Medium- and Heavy-Duty Infrastructure Map launched in 2024, aggregate public charger and hydrogen station data to aid route planning, revealing gaps in rural and intermodal hubs despite incentives from the Infrastructure Investment and Jobs Act.[81] These systems prioritize grid resilience and renewable energy integration, as evidenced by partnerships like ZE Ports in Europe, which since 2023 has financed on-site solar-powered charging for electric trucks at ports, reducing emissions by up to 90% in pilot operations.[82]
