"IT" as the Subject of the Sentence
When the pronoun "it" is used as the subject of the sentence it may represent a living being or a thing, then it is a notional subject. Sometimes, however, it does not represent any living being or thing & performs a purely grammatical function, then it is a formal subject.
The Notional Subject

can denote
The demonstrative pronoun "it"
can point out
a thing
eg. The door opened. Itwas opened by a young girl.
an abstract idea
eg. I told them about my idea. They liked it.
a person
eg. - Who is this? -It's Jonh.
a thing
eg. Itwas a large room.
a notion
eg. He came late. Itmade his father angry.
The Formal Subject
The impersonal pronoun "it"
can denote some natural phenomena
or time & distance
The introductory pronoun "it"
introduces the real subject
The emphatic pronoun "it"
emphasizes a part of the sentence
eg. It is winter. Itis stuffy here. It is 5 min past 6. It is a long way to the station.
eg. It's a shame for you to speak so. (For you to speak so is a shame.)
It is a pleasure to teach her. (To teach her is a pleasure.)
eg. It was we who went to the cinema yesterday.
It was yesterday that we went to the cinema.
It was the cinema that we went to yesterday.
The Predicate
is the second principal part of the sentence which expresses an action, state or quality of the person or thing denoted by the subject. It is grammatically dependent upon the subject. The predicate contains a finite verb.
