Re: about the pattern

Thank you, Paul!

Please let me konw the difference.

Re: about the pattern

Consider these three:

(1) She was selfish to leave without helping us.

(2) It was selfish of her to leave without helping us.

(3) To leave without helping us was selfish of her.


The difference is that (2) is called an 'extraposition' construction. This occurs when the subordinate clause subject of a non-extraposed sentence (3) is moved to the end of the sentence and replaced by the dummy pronoun "it". We call the subordinate clause in (2) an extraposed subject.

In the extraposed (2) "it" is the subject and the adjective phrase "selfish of her" is the subjective predicative complement, just as it is in the non-extraposed (3).
