السبت

السَّبْت (noun)

Etymology: Definite state of the verbal noun of سَبَتَ (sabata) meaning “to rest or hibernate”, “to cease”, “to stop or be still”, “to be motionless”, “to be quiet” as a phono-semantic matching of Classical Syriac ܫܒܬܐ (šabbəṯā, “Saturday”) used in the emphatic state; the religious sense likely being borrowed from the Hebrew שַׁבָּת (šabbā́ṯ, “weekly day of rest”). Ultimately stemming from Proto-Semitic *ṯabat- (“to be still, fixed, or staying”), doublet of the native ثَبَتَ (ṯabata). Related to Akkadian 𒋛𒁍𒌅 (se-bu-tu /⁠sebûtu⁠/, “seventh day of the month”), a holiday term that is paired with Akkadian 𒌓𒌋𒐊𒄰 (UD.15.KAM /⁠šapattu, šabattu⁠/, “two-week duration, the new and full moon”, literally “a day of the cessation”). Displaced شِيَار (šiyār).

Meaning: Saturday, the cessation or last day of the week; the Sabbath; the duration of a week, seven-day cycle
