Hi,

In the sentence, "I'm very busy.", is busy a verb or an adjective? An adjective
How can you tell? The modifier 'very' indicates 'busy' is an adjective. If in doubt, you could also look in your dictionary.

Best wishes, Clive

The verb is "am".
It can be followed by a predicate noun, predicate adjective, or the -ing form of a verb. If you see an "ing" ending, that is the clue that there is another verb!
I am playing. (play = verb)
I am happy. (happy = adjective)
I am tired. (tired = adjective)

I am a hero. (hero = noun)
