köken: Translation of Latin ālea iacta est, from Ancient Greek ἀνερρίφθω κύβος (anerrhíphthō kúbos, “let the die be cast”). See the dice is cast for more.
the die is cast (the future is already determined; the recent actions are bound to have consequences)
köken: a (“the”) + kocka (“die”) + el (“away”) + van (“is; here: has been”) + vetve (“cast”). Literally, “the die has been cast away”. El(…)vetve is the adverbial participle form of elvet (“to cast away”), with its prefix separated from the stem.
