Ditto
Ditto is an English adverb, noun, and interjection primarily used to indicate that a previous statement, item, or condition applies identically to another without requiring repetition, often abbreviated as "do." or denoted by ditto marks such as double apostrophes ('') or quotation marks ("").[1][2]
The term derives from the Italian detto, the past participle of dire ("to say"), ultimately tracing to the Latin dictum from dicere ("to say"), and entered English in the 1620s via Tuscan dialectal forms, initially in mercantile contexts to specify "the aforesaid" month or year in records and ledgers.[3][4]
By the 18th century, its usage expanded to general lists and inventories for efficiency, and in modern colloquial speech, "ditto" serves as a concise expression of agreement or similarity, as in responding to a sentiment with "Ditto!" to affirm "the same here."[4][2] The word also functions as a verb meaning to copy or repeat, though this sense is less common today outside specific contexts like early photocopying technologies branded "Ditto."[1]
