'der Affe' and 'der Primat' both belong to the area of animals and biology. 'Affe' is the normal everyday word for certain primates, for example animals in the zoo or in the rainforest. 'Primat' is more general and more scientific: it includes monkeys, apes, and humans. Learners may confuse the words because every Affe is a primate, but not every primate is an Affe. In everyday language, people usually say 'Affe'. 'Primat' is more appropriate in biology, research, or factual texts.
