(Hebrews Eyn-, עֵין , constr. of עִין, a fountain), a prefix to many names of places in Hebrews (e.g. En-gedi, En-gammin, En-dor, En-haddah, En- hazor, En-harod, En-mishpah; En-eglaim, En-shemesh, En-rogel, Entannim [Nehemiah 2:13], En-tappuah); all so called from a living spring in the vicinity; and corresponding to the Arabic prefix Ain- (Robinson, Researches, 3:225), in which language, as also in the Syriac and Ethiopic, it has the same signification; in two instances (Joshua 21:16; Numbers 34:11) it stands alone as the name of a place (q.d. "the spring"); also in the dual, ENAM (See ENAM) (q.v.), and plural ANIM (See ANIM) (q.v.), the latter likewise in the Aramaic form Enon (q.v.). (See AIN).
