The word vestry has two meanings that are more or less unrelated, though they have a common origin. A vestry is a room in which people put on vestments, or robes. A changing room. Since people typically do not take off their street clothes to put on vestments, a vestry room is not a private place but often rather more of an alcove.

A vestry can also be like a board of directors for a parish. In many provinces of the Anglican Communion, including those in the West Indies, the business affairs of a parish are managed by a vestry that consists of members elected from the congregation.

Special apparel worn in the conduct of religious services. The celebrant's Eucharistic vestment consists of the amice, alb, cincture, stole, maniple, and chasuble; a priest's or deacon's choir vestment consists of surplice, hood, and scarf. Often, each item of ecclesiastical apparel is called "a vestment." The cassock is not, strictly speaking, a
vestment.

Psalm 95 or, in American use, a canticle based on that psalm, used as the invitatory at daily Morning Prayer. (From the first word of the psalm in Latin, meaning "O come!").

"Vicar" has meaning similar to "rector." The difference between "vicar" and "rector" has to do with money. A vicar is the priest in charge of a parish or mission that is supported financially from the outside, while a rector is the priest in charge of a self-supporting church.

A clergyman who acts as the bishop's deputy in administrative matters. During the vacancy of a see (i.e., between the death or disability of the bishop and the
enthronement of his successor), the Ecclesiastical Authority may appoint an administrator to assume the duties of a vicar general; in such a case the administrator's proper title is "vicar capitular" (because he acts in place of the "chapter"--i.e., the Standing Committee--of the diocese).

A "Vicarage" is normally a house occupied by a clergyperson who usually (but not always) turns out to be a Vicar rather than a Rector.
