Converb

A converb is a non-finite verb form whose primary function is to mark adverbial subordination, connecting a dependent clause to a main clause to express relations such as simultaneity, anteriority, cause, manner, or condition.^[1] Unlike finite verbs, converbs lack independent tense, mood, and subject agreement marking, relying on the main clause for temporal and aspectual interpretation, and they often attach via specialized suffixes to verb stems or participles.^[1] Converbs form paradigmatic sets in many languages, with specialized forms encoding specific semantic nuances; for example, temporal converbs may distinguish between actions occurring before, during, or after the main event.^[1] Morphosyntactically, they exhibit adverbial behavior by modifying the main predicate without requiring additional linking words, though some languages allow adsentential uses for broader connective roles. Typologically, converbs are distinguished from infinitives by their subordinating role and from participles by their non-attributive, clause-linking function.^[1] These forms are cross-linguistically valid and widespread, occurring in about two-fifths of sampled languages worldwide, with greater prominence in object-verb (OV) word order languages.^[2]^[3] They appear in diverse families, including Indo-European (e.g., Russian, Lithuanian), Uralic (e.g., Estonian, Finnish), Turkic (e.g., Turkish, Turkmenian), Caucasian (e.g., Lezgian), Koreanic (e.g., Korean), Japonic (e.g., Japanese), Dravidian, Ethiopian Semitic, and some South American indigenous languages, spanning Europe, South and Central Asia, the Far East, Africa, and the Americas.^[1]^[4]^[5]

Terminology

Etymology

The term "converb" was coined by Finnish linguist and Altaicist Gustaf John Ramstedt in 1902, in his seminal work Über die Konjugation des Khalkha-Mongolischen, to describe a specific type of non-finite verb form in Mongolian that functions to connect clauses without independent predication. Ramstedt introduced the German "Konverb" to capture this linking role, drawing from the Latin prefix con- ("together" or "with") combined with verbum ("verb" or "word"), thereby emphasizing the form's adverbial and connective properties in chaining multiple actions within a sentence. This neologism marked a deliberate terminological innovation within early 20th-century Altaic linguistics, where such forms had previously lacked a unified label. In the 19th century, scholars studying Altaic languages, including Mongolic and Turkic varieties, referred to analogous verbal constructions using established Indo-European categories like "gerundive," "participial forms," or "verbal adverbs," often adapting terms from Latin and Greek grammar to describe their subordinate, non-finite nature.^[6] These earlier descriptors reflected the influence of classical philology but frequently led to ambiguities, as they imposed nominal or adjectival interpretations on forms that primarily served adverbial subordination. Throughout the 20th century, the adoption of "converb" gained traction beyond Altaic specialists, particularly from the 1970s onward, as typologists sought to differentiate these structures from Indo-European non-finites like gerunds (which often nominalize actions) and participles (which modify nouns adjectivally). This shift, accelerated by cross-linguistic comparisons in works such as those by Igor Nedjalkov (1995), underscored the converb's unique role in encoding dependent adverbial clauses, avoiding the Eurocentric biases of traditional terminology and facilitating broader typological analysis.^[7] By the late 20th century, the term had become standard in descriptions of non-finite verb forms across Eurasian languages, reflecting a move toward more precise, function-based categorization.

Definition

A converb is a non-finite verb form whose primary function is to mark adverbial subordination, linking a dependent clause to a main clause by expressing relations such as simultaneity, anteriority, or causality.^[1] This form typically consists of a verb stem combined with a specific affix, enabling it to function adverbially without the full inflectional properties of finite verbs.^[1] Key criteria for identifying a converb include its role as a marker of clause subordination, the absence of independent tense, mood, or person-number agreement, and its inability to serve as the sole predicate of an independent sentence.^[1] Unlike finite verbs, which exhibit subject-verb agreement and can license nominative case on subjects while standing alone, converbs are inherently dependent, requiring a finite main verb to complete the predication and often sharing the subject with the main clause.^[1] These characteristics distinguish the converb as a dedicated grammatical category for encoding adverbial dependency, emphasizing its syntactic subordination over nominal or infinitival functions.

Linguistic Features

Syntactic Roles

Converbs primarily function as adverbial subordinates within sentence structures, modifying the main verb or clause by expressing relations such as manner, time, condition, or cause. This role enables the integration of dependent clauses that provide circumstantial information to the primary action, often without explicit conjunctions, thereby enhancing clause cohesion in complex sentences. For instance, a converb clause might indicate the temporal sequence or causal basis for the event in the matrix clause, distinguishing converbs from finite verbs that carry independent illocutionary force. A key syntactic application of converbs is in clause chaining, particularly prevalent in agglutinative languages of Asia and beyond, where they link a series of dependent clauses depicting sequential or concomitant actions culminating in a final independent clause. This chaining mechanism supports narrative progression by allowing multiple predications to share subjects and tense-aspect-mood features, facilitating efficient expression of event sequences without repeated finite verb marking. Such constructions are especially adaptive for foregrounding chains of events in discourse. Syntactically, converbs exhibit significant restrictions that underscore their dependent status: as non-finite forms, they cannot serve as the head of an independent clause or bear full predicative force on their own. Additionally, converbs typically do not govern direct objects independently, instead sharing arguments with the matrix clause or limiting nominal dependencies to suit their adverbial role, which prevents them from functioning as full verbal predicates. These constraints ensure converbs remain tightly integrated into larger clausal structures rather than standing alone.

Morphological Characteristics

Converbs constitute a category of non-finite verb forms characterized by their inability to serve as the primary predicate in an independent clause and their lack of inflection for person or number agreement with a subject. Unlike finite verbs, they do not independently express tense, mood, or illocutionary force, though they may incorporate limited tense-aspect marking dependent on the main clause. This non-finite status positions converbs on a morphological cline between fully finite and nominal forms, emphasizing their verbal yet subordinate nature.^[8]^[9] Morphologically, converbs are typically derived from the verb stem through suffixation, a process that applies productively across many languages employing this category. These suffixes result in fixed stem modifications without altering the core lexical meaning of the verb, distinguishing converbs from more flexible finite inflections. The non-finite morphology ensures that converbs function adverbially, often linking clauses without requiring additional case or agreement markers on associated arguments.^[8]^[9] Languages with converbs frequently distinguish multiple types through dedicated suffixes that convey semantic nuances related to temporal or aspectual relations, such as simultaneous converbs (indicating actions occurring concurrently with the main clause event) versus anterior converbs (denoting actions completed prior to the main event). Other common variants include terminative forms (marking actions up to a point of completion) and conditional forms (expressing hypothetical or cause-effect relations). These specialized markers allow for precise adverbial subordination while maintaining the overall non-finite profile of the form.^[8]

Distribution and Typology

Languages Employing Converbs

Converbs are attested in Turkic, Mongolic, and Tungusic languages, spoken across Central Asia and Siberia.^[7] In these languages, converbs serve as key non-finite verb forms for linking dependent clauses, with examples such as the gerunds in Turkish (a Turkic language) and adverbial participles in Evenki (a Tungusic language).^[7] This distribution aligns with the historical and geographical spread of these languages from the steppes of Mongolia to the forests of eastern Siberia, where converbs facilitate complex sentence structures in oral traditions and narratives.^[10] Beyond these, converbs extend to languages in other families, including Uralic (e.g., in Finnish and Hungarian for adverbial subordination), Dravidian (e.g., in Malayalam for clause conjoining), Caucasian (e.g., Lezgian), Koreanic (e.g., Korean), Japonic (e.g., Japanese), some Papuan languages (e.g., in verb-final structures of New Guinea languages), Ethiopian Semitic (e.g., Amharic), and some indigenous languages of South America.^[7]^[1] Converbs are less prominent in Indo-European languages than in Asian families, but they are attested in some, such as Russian and Lithuanian, where analogous functions are often handled by participles or infinitives.^[7]^[1] Typologically, converbs are widespread, occurring in about two-fifths of sampled languages worldwide, with greater prominence in object-verb (OV) word order languages.^[2]^[3] They predominate in agglutinative languages, such as those in the Turkic and Dravidian families, where suffixation allows precise marking of subordination without fusion of morphemes.^[7] They are also prevalent in head-marking languages, which encode grammatical relations on verbs rather than nouns, enabling efficient poly-clausal constructions in discourse-heavy genres.^[7] This pattern correlates with object-verb (OV) word order, common in Asian and Siberian languages, where converbs precede the main verb to build chained clauses expressing temporal, causal, or conditional relations.^[11]

Comparison to Other Verb Forms

Converbs differ fundamentally from infinitives in their syntactic roles and morphological properties. While infinitives typically function as arguments, serving as subjects, objects, or obligatory complements in clausal structures, converbs operate strictly as adverbial adjuncts, marking optional subordination without nominalizing the verb action.^[6] This distinction arises because infinitives often derive from purposive action nominals and retain some verbal-noun characteristics, allowing them to integrate into noun phrases, whereas converbs lack such nominal properties and emphasize adverbial dependency in clause chaining.^[12] For instance, the obligatoriness of infinitives in complement positions contrasts with the free, non-argumental positioning of converbs, which do not govern or complement but modify the main clause adverbially.^[1] In comparison to participles and gerunds, converbs exhibit a more specialized adverbial function rather than adjectival modification or nominalization. Participles, as verbal adjectives, primarily attribute qualities to nouns in attributive or predicative roles, agreeing in features like tense, aspect, or case with the head noun they modify.^[6] Gerunds, akin to action nominals, function as verbal nouns capable of taking nominal inflections such as case or determiners, enabling them to appear in argument positions or as heads of noun phrases. Converbs, by contrast, do not modify nouns adjectivally nor exhibit nominal morphology; instead, they chain clauses sequentially through adverbial subordination, focusing on interclausal relations like simultaneity or anteriority without altering the nominal status of surrounding elements.^[12] This sequential chaining role underscores their unique position among non-finites, prioritizing adverbial connectivity over descriptive or substantive functions.^[1] Supines represent another point of contrast, particularly in their emphasis on purpose or result over the aspectual and relational aspects central to converbs. Supines, a rare non-finite form preserved in languages like Latin and some Slavic varieties, often serve as complements to verbs of motion or perception, expressing purpose in a manner akin to infinitives but with distinct morphological markers, such as the accusative -um in Latin for directional purpose.^[13] Unlike converbs, which highlight aspectual relations like precedence or simultaneity in adverbial chains, supines focus on teleological complementation and lack the broad adverbial subordinating capacity of converbs.^[6] This functional divergence positions supines closer to infinitival complements, reinforcing the adverbial exclusivity of converbs in facilitating dependent clause linkage without purposive intent.^[12]

Case Studies

Khalkha Mongolian

Khalkha Mongolian exemplifies a prototypical converb system within the Mongolic languages, where non-finite verb forms facilitate adverbial subordination and clause chaining without finite marking for tense or mood. The system includes four primary converbs that encode aspectual and temporal nuances: the imperfective converb marked by the suffix -aa, the perfective converb with -san, the terminative converb using -tal, and the conditional converb formed by -ge. These forms derive from the verb stem through suffixation, adhering to vowel harmony rules inherent to Khalkha phonology, and they cannot inflect for person, number, or case on their own.^[14] The imperfective converb -aa typically conveys ongoing or simultaneous actions relative to the main clause, often serving as a background or manner modifier, while the perfective -san indicates completed actions preceding the matrix verb, emphasizing anteriority. The terminative -tal denotes actions extending up to a specific endpoint or limit, and the conditional -ge expresses hypothetical conditions or concessions leading into the main proposition. Unlike participles, which can nominalize verbs, these converbs remain strictly verbal and adverbial, integrating seamlessly into complex sentences to avoid full subordination via conjunctions.^[15] A key function of these converbs lies in their role for action chaining in sequential narratives, where multiple converbial forms precede a single finite verb to depict a series of linked events, such as yav-aa, xar-aa, buu-san ("going, seeing, returning") to narrate a journey's progression. This chaining mechanism supports compact expression of temporal sequences without repeated subjects or connectives, enhancing discourse flow in spoken and written Khalkha.^[16]^[17] In syntactic structure, converbs govern dependent clauses where the subject remains in the nominative case, identical to the main clause subject for same-subject constructions, thereby permitting efficient coreference without accusative or genitive marking that would signal switch-reference. This nominative retention underscores the dependent yet coordinated nature of converbial clauses in Khalkha syntax.

Standard Uzbek

In Standard Uzbek, converbs are non-finite verb forms that primarily function to connect clauses in adverbial subordination, expressing relationships such as simultaneity, conditionality, and duration. The key converb suffixes include -ib, which marks simultaneous actions; -ganda, which indicates conditional or temporal relations; and -guncha, which denotes durative aspects with an endpoint.^[18] Converbs in Standard Uzbek facilitate clause subordination, particularly for temporal and causal links, allowing complex sentences without finite verb repetition. The -ib suffix, for example, links simultaneous or sequential actions in daily speech, as in U kitob o'qib, choy ichdi ("He drank tea while reading a book"), creating a temporal overlap.^[19] Similarly, -ganda expresses conditional or temporal causation, such as Men seni ko'rganimda, xursand bo'ldim ("When I saw you, I was happy"), subordinating the clause to imply a causal trigger.^[20] The -guncha suffix extends this to durative subordination, marking ongoing actions up to a point, as in Ishlab tur-guncha, dam olmadi ("He didn't rest until he finished working"), highlighting persistence in proverbs like those emphasizing diligence in Uzbek folklore.^[18] These forms are prevalent in both spoken narratives and literary expressions, enabling concise chaining of events.^[20]

Turkish

In Turkish, converbs function as non-finite verbal forms that primarily serve adverbial roles in subordinate clauses, enabling the expression of temporal, aspectual, and modal relations relative to the main clause without requiring finite verb agreement.^[21] These forms are morphologically distinct from finite verbs and participles, typically attaching directly to the verb stem and exhibiting vowel harmony, a hallmark of Turkic agglutinative morphology.^[21] Unlike full clauses, converbs in Turkish are obligatorily controlled in certain types, meaning their subjects must corefer with the main clause subject, though others allow independent subjects.^[21] Key converb forms include the simultaneous converb -erek/-arak, which denotes actions occurring concurrently with or in the manner of the main verb, often used to describe accompanying circumstances. For instance, in the sentence Okula giderken Cem bizi aradı ("Cem called us while going to school"), -erken (a variant of -erek) indicates simultaneity.^[22] This form is morphologically simple, suffixing to the verb stem with present tense or aspect markers like -Ir or -mIş, and it frequently appears in narrative chaining to advance sequences without temporal gaps.^[23] Another prominent form is the posterior converb -ince, which signals that the subordinate action precedes the main clause event, akin to "after" or "when" in English, as in Çocuk eve gelince yemek yedi ("When the child came home, s/he ate").^[22] This suffix attaches directly to the verb stem and permits non-coreferential subjects, making it versatile for sequential events in complex sentences.^[21] The iterative converb -dikçe expresses repetition or continuation, often conveying "as" or "each time" in ongoing processes, exemplified by Kitabı okudukça merakım artar ("Whenever I read the book, my curiosity increases").^[22] Morphologically, it combines the past tense marker -dI with -çe for durative emphasis, and it is tense-independent, allowing integration into various aspectual frames.^[21] These converbs commonly function as manner adverbials in modern Turkish, embedding descriptive actions within main clauses, such as Koşarak geldi ("Running, he arrived"), where the converb clause provides circumstantial detail without conjunctions.^[22] Historically, Turkish converbs evolved from Old Turkic prototypes, where a richer inventory of B-type converbs (e.g., -ip for chaining) dominated for narrative and modal purposes, but Modern Turkish saw the loss of some forms in favor of participles and new aspectual markers like the progressive -Iyor-.^[23] This simplification arose through grammaticalization paths in postverb constructions (converb + auxiliary), where lexical verbs like "sit" or "stand" bleached into tense-aspect operators, reducing reliance on older converbal types.^[23] For example, Old Turkic sequences like sub-ïn ïd-ïp tabγač-γaru bar-dï ("having done so, went to China") evolved into streamlined modern forms using -erek/-arak for similar sequentiality.^[23] In contemporary usage, these developments have streamlined Turkish subordination, prioritizing efficiency in spoken and written discourse while retaining core adverbial functions.^[22]
