The process or fact of finally happening; the ultimate outcome or result.
From 'eventuate' plus the noun-forming suffix '-tion' (from Latin '-tio'). Created in English to nominalize the concept of something ultimately occurring.
Abstract nouns ending in '-tion' are incredibly common in English (nation, creation, station), and they often come from Latin—which is why formal, academic English uses so many '-tion' words while casual speech uses simpler verbs like 'happen.'
