How to form Exclamatory 'How!' sentences
Exclamatory 'how' sentences are formed in this way: 'How + adjective/adverb!'
To form a 'how' exclamatory phrase with someone or something, you can say 'how [adjective] of someone/something'.
How kind of the young man!
You can add an infinitive verb phrase to explain a reason for your exclamation:
- How kind of the young man to help the old man cross the street!
- How rude of the man to talk on his phone during the movie!
If you replace the person/thing you are talking about, make sure to use an object pronoun: 'How kind of him!' (not 'he').
