What language origin does the word "God" come from?

Answer 1

Among the Hebrew words that are translated “God” is ’El, probably meaning “Mighty One; Strong One.” (Ge 14:18) It is used with reference to Jehovah, to other gods, and to men. It is also used extensively in the makeup of proper names, such as Elisha (meaning “God Is Salvation”) and Michael (“Who Is Like God?”). In some places ’El appears with the definite article (ha·’El′, literally, “the God”) with reference to Jehovah, thereby distinguishing him from other gods.—Ge 46:3; 2Sa 22:31
The plural form, ’e·lim′, is used when referring to other gods, such as at Exodus 15:11 (“gods”). It is also used as the plural of majesty and excellence, as in Psalm 89:6: “Who can resemble Jehovah among the sons of God [bi·beneh′ ’E·lim′]?”
The Hebrew word ’elo·him′ (gods) appears to be from a root meaning “be strong.” ’Elo·him′ is the plural of ’eloh′ah (god). Sometimes this plural refers to a number of gods (Ge 31:30, 32; 35:2), but more often it is used as a plural of majesty, dignity, or excellence.
