The word is thought to be derived by contraction from al - ilāh, which means "the god", and is linguistically related to the Aramaic words Elah and Syriac ܐܲܠܵܗܵܐ (ʼAlāhā) and the Hebrew word El (Elohim) for God.

Etymologically, the name Allah is probably a contraction of the Arabic al-Ilāh, “the God.” The name’s origin can be traced to the earliest Semitic writings in which the word for god was il, el, or eloah, the latter two used in the Hebrew Bible (Old Testament).

First, the word “allah” is understood specifically as the Muslim god by Hebrew speaking people despite its common root. Second, the word “elohim” is understood in Hebrew as a generic noun for “god/gods;” ‘elohim’ in Hebrew is used almost identically to the way ‘allah’ is used in Arabic.

The normal generic word for God is "alaha"/"aloho" (ܐܠܗܐ), which is linguistically related to the Hebrew word for God "elohim".

El in Hebrew means god, and Elah or Eloh also stands for the same name - god. Therefore, "Huwa el Elah" or HUWA 'L LAH, which is identical to the Quranic expression - Huwal lah hu (meaning: HE IS ALLAH) of the verse QUL HUWAL LAH HU
