Brit.

/ˈsʌbɪntəvl/, U.S.

Origin: Formed within English, by derivation. Etymons: sub- prefix, interval n.

Etymology: < sub- prefix + interval n.

Chiefly Mathematics.

A subdivision of an interval between two times, numerical values, etc.; (also) an interval forming a subset of another interval (interval n. 7b).
