Where it comes from

Learned borrowing from Latin fortuītus (“happening by chance, accidental, random, fortuitous”), from *fortu- (“chance, fortune, luck”) + -ītus (suffix forming adjectives). *Fortu- is thought to be from *fortus, from fors (“chance, luck”) (ultimately from Proto-Indo-European *bʰer- (“to bear, carry”)) + -tus (suffix forming action nouns). Doublet of fortuity.
