En

at the beginning of many Hebrew words, signifies a spring or fountain.

(`ayin (compare Arabic `Ain)):

The Hebrew word for "spring" or "fountain" (Ge 16:7; Nu 33:9; Ne 2:14; Pr 8:28 (feminine plural)). It occurs in numerous compound words, as EN-GEDI, EN-HADDAH, EN-HAKKORE, EN-HAZOR, EN-RIMMON, EN-ROGEL, EN-SHEMESH (which see). In the same way the word `Ain is a very common component of Arabic names of places throughout Palestine and Syria at the present day. Places with names compounded with "En-" were almost certainly located near a spring.
