'der Begriff' and 'das Synonym' both belong to the area of language and meaning, but they are not the same thing. A 'Begriff' is a word or phrase that denotes a specific idea. A 'Synonym' is another word with the same or a very similar meaning. They can be confused because both involve talking about words. But 'Begriff' asks about the meaning or concept itself. 'Synonym' asks for another suitable word for the same or almost the same content.
