Sabbath

Origin

From Middle English sabat, sabbat, sabath, from Old English sabat and Old French sabbat, both from Latin sabbatum, from Ancient Greek σάββατον (sábbaton, “Sabbath”), from Hebrew שַׁבָּת (shabát, “Sabbath”), with the spelling ending in -th, probably influenced by the traditional transliteration of the Hebrew as shabbāth, being attested since the 14th century and widespread since the 16th. Doublet of Shabbat. Possibly from the Sumerian sa-bat ("mid-rest").
