XIII. On the word “Mass:” By John Bruce, Esq. In a Letter to Thomas Amyot, Esq. F.R.S. Treasurer

The derivation of the word “Mass” having lately been the subject of our conversation, I am induced to offer you the following Remarks upon it, from which I think it will appear that the word, as used to signify the service of the Roman Catholic Church, is wholly distinct, both in derivation and sense, from “mas” the adjunct to Christ, &c. in the words, “Christmas,” “Candlemas,” “Lammas,” &c. In the former sense it seems to come from the Latin “Missa,” and in the latter from the Anglo-Saxon “mærre;” the one having been used in the early ages of the Church as a word of dismission to the congregation, or a part of it, and the other signifying a feast or solemn festival.
