Word Origin & History

sentry
1611, originally "watchtower;" perhaps a shortened variant of sentinel (q.v.), which had a variant form centrinel (1598), or worn down from sanctuary, on notion of "shelter for a watchman." Meaning "military guard posted around a camp" is first attested 1632. Sentry-box is from 1728.
