early 15c., "to shut (someone or something) in materially, enclose, imprison, confine," also "to have (something) as a constituent part," from Latin includere "to shut in, enclose, imprison, insert," from in- "in" (from PIE root *en "in") + claudere "to shut" (see close (v.)). The alleged Sam Goldwyn-ism "Include me out" is attested from 1937. Related: Included; including.
