Forms
bis (not comparable)[1] Cicero cites the old form duis; it is sometimes written as one word with sēnī.[2][3]
Etymology
It is from Old Latin ⟨duis⟩, inherited from Proto-Italic *dwis, inherited from Proto-Indo-European *dwís (“twice”), an adverb from *dwóh₁ (“two”).[3][1][2] Cognates include Sanskrit द्विस् (dvís), Avestan biš and Ancient Greek δίς (dís), all “twice”.[3][2]
Earliest recorded meaning
De Vaan dates it from Plautus.[3][2] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
It meant on two occasions, twice, as in Plautus and Cicero's bis in diē “twice a day”; with numerals two times, as in bis mīlle; in twofold degree, doubly; and perhaps for the second time, in Martial.[2][5] The distributive bīnī “two each” is from it.[3]
In Ecclesiastical Latin it meant twice.[6] British Medieval Latin used it for twice and twice as many.[7]
