introit

Imagine stepping into a grand cathedral. The first music you hear, the piece that welcomes everyone and sets the tone for the service, is an introit. In its main sense, it is a chant, hymn, or anthem sung at the beginning of a church service, especially as the clergy enter. The word can also be used more broadly for a formal opening piece, but that use is much less common. Most of the time, if you see "introit," it is talking about worship, music, and the start of a religious ceremony.

The word "introit" has a long history in Christian worship. In its traditional meaning, it refers to the psalm, antiphon, chant, hymn, or anthem used at the opening of a service, especially during the entrance of the clergy. It is most strongly linked with the Roman Catholic Mass, where the introit belongs to the entrance rite, but the word is also used in other liturgical traditions for similar opening music. The term comes from the Latin introitus, meaning "entrance."

By extension, "introit" can sometimes describe a formal introduction or opening section in a more general setting, especially in writing or in artistic description. Still, that wider use is not the usual one. Native speakers rarely use it for everyday openings like a casual chat, a first paragraph, or a simple conversation starter. In normal modern English, the word keeps a clear church or ceremonial feeling.

So if you hear about an introit, picture the beginning of a service: people entering, music rising, and the ceremony being gently opened. In a few cases, the word may point to another formal opening, but its core meaning remains an opening chant or hymn connected with worship.
