Usage tips
Sentence structure and usage
'Atheist' (atheist) is a noun, but it is often used like an adjective after the verb 'sein' (to be). In this case, it appears without an article, similar to professions or nationalities.
EXAMPLE
Obwohl seine Familie sehr religiös ist, ist er Atheist.
Although his family is very religious, he is an atheist.
Word family
The word family includes 'der Atheismus' (atheism, the worldview) and the adjective 'atheistisch' (atheistic). The adjective is used before a noun to describe it.
EXAMPLE
Er vertritt eine atheistische Position in der Debatte.
He represents an atheistic position in the debate.
Word structure
The word comes from Greek: the prefix 'a-' means 'not' or 'un-', and 'theos' means 'God'. So an atheist is literally a person who does not believe in a god.
EXAMPLE
Die Herkunft des Wortes Atheist aus dem Griechischen erklärt seine Bedeutung sehr gut.
The origin of the word atheist from Greek explains its meaning very well.

Atheist vs gläubig
devout / credulous
'gläubig' and 'der Atheist' are opposites in the religious sense. A 'gläubig' person believes in God or in the teachings of a religion. An atheist does not believe in the existence of a god. What matters here is only the religious meaning of 'gläubig', not the meaning 'trusting naively'. So when talking about religion, you say: someone is 'gläubig' if religion plays a role for them; someone is an atheist if they do not believe in any god.
Atheist
