Synonyms do they have words that have the same meaning words have opposite meanings. Words are the same part of speech.

Yes, synonyms are words that have the same or similar meanings. They can be used interchangeably in most contexts. Antonyms, on the other hand, are words that have opposite meanings. They express contradictory or contrasting ideas. For example, "hot" and "cold" are antonyms. Synonyms and antonyms can both belong to the same part of speech, but they can also cross different parts of speech. For instance, the noun "freedom" has the synonymous verb "liberate" and the antonymous verb "restrict."
