to affirm, approve, answer something in the affirmative
çekim: geçmiş bejahte · ortaç bejaht · şimdiki bejaht · ulaç bejahend
eş: Ja, sagen, zustimmen
zıt: verneinen
köken: 16th century, equivalent to be- + ja (“yes”) + -en (with -h- as orthographic hiatus breaker). While the verb may have been derived directly from the interjection ja, an alternative possibility is that it is a reinterpretation of Middle High German bejëhen (“to acknowledge, admit”), from jëhen (“to say”). The according spelling bejähen is indeed attested in the 17th century.
köken: First attested in 1380, from Old French oïl (1100), from Vulgar Latin *hoc ille or by surface analysis a compound of Old French o (affirmative particle) and il (“he”). Partially cognate to Occitan òc (“yes”) and Catalan oi (“isn't it?”). See the Old French term for details.
aile: mais oui, ni oui ni non, pour un oui ou pour un non
an intensifier; corresponds to the English auxiliary do in many cases · enough, sufficiently
köken: From Proto-Finnic *küllä. Cognates include Estonian küll, Ingrian kyl, Karelian kyllä, Livonian ki’l, Veps külläine (“content, fat”) and Votic küll. Also related to Northern Sami galˈle. The adverb developed from the noun, while the interjection developed from the adverb, perhaps under Germanic influence (see usage notes).
köken: Inherited from Old Czech ano, from Proto-Slavic *ano. Compare Slovak áno (“yes”), Polish ano (“yes, indeed”). First attested in the 15th century.
