saint

From Middle English saint, seint, sainct, seinct, sanct, senct, partly from Old English sanct (“saint”) and confluence with Old French saint, seinte (Modern French saint); both from Latin sānctus (“holy, consecrated”, in Late Latin as a noun, “a saint”), past participle of sancīre (“to render sacred, make holy”), akin to sacer (“holy, sacred”). Doublet of Sanctus. Displaced native Middle English halwe (“saint”) from Old English hālga (“saint, holy one”) (> Modern English hallow (“saint”)).

From Middle English saynten, seinten, sonten, partly from Anglo-Norman saintir and partly from the noun Middle English seint, seynt (see above).
