atheistic

The word 'atheistic' is built upon the Greek negation prefix a- and the root theos, meaning "god." The core term atheos in ancient Greek literally meant "without god," describing someone who denied the gods recognized by the state or society. This concept passed into Latin as atheus and later into French, where the suffix -iste (denoting an adherent) was added to form athéiste. The English adjective 'atheistic' incorporates the additional adjectival suffix -ic, which ultimately derives from the Greek -ikos. Thus, the term's literal construction, "pertaining to being without god," directly and logically reflects its modern philosophical meaning of denying or disbelieving in the existence of any deity.
