atheist
UK: ˈeɪθiɪst | US: ˈeɪθiɪst
n. a person who disbelieves or lacks belief in the existence of God or gods
The word "atheist" originates from the Greek prefix "a-" (meaning "without") combined with "theos" (meaning "god"), and the suffix "-ist" (indicating a person who holds a belief or practice). The term emerged in the 16th century to describe individuals who rejected belief in deities, reflecting a direct negation of theism (belief in gods). The morphemes preserve their original Greek roots while forming a cohesive English term.
