Noun and Adjective forms in English 

Do you say “She is intelligent” or “She is intelligence”? 

If you chose intelligent, you’re right and you’re using the adjective, not the noun. 

Getting nouns and adjectives mixed up is a common mistake for English learners, and it can make your sentences sound unnatural. This quick guide will help you spot the difference and build your vocabulary with more confidence. 

What’s the Difference? 

• A noun names a person, place, thing, idea, or feeling. (anger, beauty, intelligence) 
• An adjective describes or gives more information about a noun. (angry, beautiful, intelligent)

Knowing which form to use helps you sound clearer and more natural when speaking or writing in English. 

Examples in Context: 

• He showed great strength during the match. (noun) 
• He is a strong player. (adjective) 
• This soup has a lot of warmth. (noun) 
• It feels warm and comforting. (adjective)

Tip: The more you read, write, and listen to English, the more naturally these forms will come to you. Try writing your own example sentences using some of the pairs above — it’s a great way to lock them into memory.
