Theonym
A theonym, from Greek theos, meaning "god", and όνομα, meaning "name", is a proper name of a deity. Theonymy, the study of divine proper names, is a branch of onomastics; it helps develop an understanding of the function and societal views of particular gods and may help undertand the origins of a society's language.
Analysis of theonyms has been useful in understanding the connections of Indo-European languages, and possibly their religion.
In all languages, analysis of the possible etymological origin of a theonym can serve as basis for theories of its historical origin.
Metaphysical and mystical meanings are also discerned in theonyms, as in Kabbalah.
Theonyms can also appear as all or part of a name for a human, animal, thing or place.
