momentaladj.

Brit.

/mə(ʊ)ˈmɛntl/, U.S.

/moʊˈmɛn(t)l/,

/məˈmɛn(t)l/

Forms: 1600s momentall, 1700s– momental.

Origin: Formed within English, by derivation. Etymons: moment n., -al suffix¹; momentum n.

Etymology: < moment n. + -al suffix¹. With sense 1 compare French †momental ephemeral, provisional (1611 in Cotgrave; compare Middle French momentel (15th cent. in an isolated attestation)), post-classical Latin momentalis (12th cent. in a British source; compare earlier momentaliter , adverb, 6th cent.). In sense 2a probably independently < momentum n. + -al suffix¹.

†1. Lasting only a moment; momentary. Obsolete.
