late 14c., Biblical, from Late Latin Baal, Greek Baal, from Hebrew Ba'al, literally "owner, master, lord," a title applied to any deity (including Jehovah; see Hosea ii.16), but later a name of a particular Semitic solar deity worshipped licentiously by the Phoenecians and Carthaginians; from ba'al "he took possession of," also "he married;" related to or derived from the Akkadian god-name Belu (source of Hebrew Bel), name of Marduk. Identical with the first element in Beelzebub and the second in Hannibal ("grace of Baal"), Hasdrubal ("help of Baal"). The name has been used figuratively in English for any "false god."
