Pronunciation
Forms
introitus m (genitive introitūs); fourth declension[1] Inscriptions have an ablative singular introitō and plural introitīs.[2]
Etymology
It is from Latin introeō (“to go in”) + -tus.[2][1][3] The verb is formed from intrō (“inside”) and eō (“to go”), which goes back to Proto-Indo-European *h₁ey- (“to go”).[4]
Earliest recorded meaning
Köbler's first source is Cicero,[5] who distinguishes keeping a man from entering a place and keeping him from approaching it at all.[2]
Semantic evolution
It is a going in, an entrance, and in Cicero also a hostile entry, as Marcellus' entry into Syracuse.[2] It is also a means or right of entry, a way in or entrance, and in geography the mouth of a river or harbour.[2][6] Pliny the Younger uses it of entry into a council and the fee paid for it.[2] Figuratively it is a beginning or introduction, as Cicero's opening of a defence.[2][6]
In Church Latin it is the introit, the chant sung as the priest approaches the altar.[7][1][8] Medieval texts also use it of entry into an office, of a relief paid to a lord, of an import duty and of revenue.[7]
