Etymology

From Proto-Italic *som~*ezom, from Proto-Indo-European *h₁ésti (“be”) + *bʰúHt (“become”). From the latter of the two derive all the /f-/ forms of Latin sum (including fore), the separate verb fīō (“become”), and the verb-endings -bō (future) and -bam (past imperfect). Clipped conjugations with /s-/, such as sum itself, occurred alongside more conservative equivalents with /es-/ in early Latin, such as the archaic esum. The clipped forms likely arose as unstressed clitics.
