eş: comme ça, c’est pourquoi, de ce fait, donc, du coup, en conséquence
köken: Inherited from Middle French ainsi, from Old French ensi, ainsins, probably from Latin ad (“to”) + in (“in”) + sīc (“thus”). Alternatively, from Old French ains + si, but this is less likely, especially for the forms beginning with en-. Compare Catalan així, Italian così, Portuguese assim, Romanian așa, Spanish así.
aile: ainsi que, et ainsi de suite, pour ainsi dire
Ainsi, je conclus que son comportement était délibéré.
köken: From Byzantine Greek ἀφοῦ (aphoû), from Koine Greek ἀφ’ (aph’) and οὗ (hoû), from Ancient Greek ἀπό (apó) and οὗ (hoû, masculine genitive singular of the relative pronoun).
köken: Equivalent to an adverbial derivation from *ēregō, presumably ex- + regō, with sense similar to cognate pergō (“to proceed”). See also ergā. Compare with the adverbial use of ē regiōne (“directly, against”), with the same elements.
