anarthrous

A false, coined, fake, bogus or pseudo-title, also called a Time-style adjective and an anarthrous nominal premodifier, is a kind of appositive phrase before a noun; it resembles a title in not starting with an article but is not a title.

Daniel B. Wallace argues that the use of the anarthrous theos (the lack of the definite article before the second theos) is due to its use as a qualitative noun, describing the nature or essence of the Word, not due to Colwell's rule.
