See, e.g., William L. Holladay, ed., A Concise Hebrew and Aramaic Lexicon of the Old Testament, (Leiden: Brill, 1971) s.v., 360. According to Edward Mahler the verb shabbat does not mean "to rest" but "to be complete." The noun shabbat means in Babylonian a cycle in a chronological sense, the day on which the moon completes its cycle, the day of the full moon.
