- n. The service or sacrifice of the Mass.
from The Century Dictionary and Cyclopedia
- n. The mass; a mass.
- n. In the Mozarabic liturgy, a variable prayer or address, called more fully the Oratio Missœ (Prayer of the Mass), answering to the Gallican Præfatio Missœ (Preface of the Mass). It probably derived its name from the fact that the dismissal (missa) of the catechumens originally preceded it.
From the Latin phrase "Ite, missa est,", "Go, it is the dismissal (or sending)", reinterpreted as naming the ceremony: "Go, it is the Mass" or "Go, the Mass is over"; from perfect passive participle missus, dismissal or sending, from verb mittere, send (Wiktionary)
