Word Origin & History

O.E. scyttan "to put in place so as to fasten a door or gate," from W.Gmc. *skutjanan (cf. O.Fris. schetta, M.Du. schutten "to shut, shut up, obstruct"), from P.Gmc. *skut- "project" (see shoot). Meaning "to close by folding or bringing together" is from mid-14c. Sense of
"to set (someone) free (from)" (c.1500) is obsolete except in dialectal phrases such as to get shut of. Colloquial shut-eye for "sleep" is from 1899. To shut (one's) mouth "desist from speaking" is recorded from 1340. Shut up (v.) first recorded 1840. Shut-in "person confined from normal social intercourse" is from 1904. Shut out in baseball sense is from 1881 (v.), 1889 (n.).
