PIE word *h₁én From Late Middle English introite (“act of entering in or into, entrance; place of entrance”), borrowed from Anglo-Norman introït, introïte (“introit”), or from its etymon Latin introitus (“act of entering in or into, entrance; passage; place of entrance; (figuratively) beginning, introduction, prelude”), from introeō (“to enter, go in”) + -tus (suffix forming action nouns from verbs). Introeō is derived from intrō (“to enter, go into”) (ultimately from Proto-Indo-European *h₁én (“in”)) + eō (“to go”) (ultimately from Proto-Indo-European *h₁ey- (“to go”)).
