Pronounced as (IPA)

[kõːˈfɛs.tĩː]

Analyzable as con- + *fes + -tim, built on the same root as the verb festīnō (“to hasten”). De Vaan, citing Schrijver, identifies the root as *bʰris-, alleged to also be the source of Welsh brys (“speed, haste”). If this etymology is correct, the Latin form developed a syllabic resonant (*-r〭-) which was then replaced with *-er-, and the resulting cluster *-rst- was then regularly simplified to -st- (compare testis). The ending comes from the adverbial accusative of a deverbal noun, which De Vaan reconstructs as Proto-Indo-European *bʰristi-, Proto-Italic *fristi- (“haste”).
