1426, from L. intermissionem (nom. intermissio) "interruption," from intermissus, pp. of intermittere "to leave off," from inter- "between" + mittere "let go, send."
"Intermission is used in U.S. for what we call an interval (in a musical or dramatic performance). Under the influence of LOVE OF THE LONG WORD, it is beginning to infiltrate here and should be repelled; our own word does very well." [H.W. Fowler, "Modern English Usage," 1926]
