The word "El" comes from the root word meaning "might, strength and power". In scripture, the primary meanings of this root are "god" (pagan or false gods), "GOD" (the true God of Isreal), and sometimes "the mighty", (referring to men or angels.
When used of the true God of Isreal, EL is almost always qualified by additional words that define the meaning and distinquish him from false gods. These other names or titles for God are called 'construct forms".
Some examples are;
EL (basic form)
El Echad - The One God (Mal. 2:10)
El Emet - The God of Truth (ps. 31:5)
El Tsaddik - The righteous God (Isa. 45:21)
El Yisreal - The God of Isreal (Ps. 68:36)
El Elyon - The most high God (Gen. 14:20, Ps. 9:2)
