Question

which source helps you find words that mean the same as other words? a dictionary b glossary c thesaurus

Explanation:

• A dictionary primarily gives definitions, pronunciations, and sometimes etymologies of words, not mainly synonyms.
• A glossary is a list of terms with their definitions, usually specific to a subject, and does not focus on synonyms.
• A thesaurus is a reference work that lists words grouped together according to similarity of meaning (synonyms) and sometimes also antonyms. So it helps find words with the same meaning as other words.

Answer:

C. thesaurus
