I can’t understand that how do we use of after adjectives ?
- It was beautiful of you to…
- It was kind of you to…
- It was generous of you to…
As I know, it is possible to use of after “nouns”.
- It was beauty of you to…
- It was kindness of you to…
- It was generosity of you to…
But how can that be possible in terms of adjectives?
Best Answer
of you refers to "you" (him, her, them, etc) as possessing a quality or attribute.
You have behaved in a way that is characterized by an adjective and that attribute is then attributed to you (her, him, etc).
The (possibly optional) complement specifies the action or behavior in the form of a non-finite clause:
The non-finite clause supplies the idea-content for it exposed at the head of the sentence.
It (i.e. "to say so") was kind of you.
If the thing to which it refers is already established in context, the non-finite clause is not needed:
With the noun, we would say on your part instead of of you.
