I Think is perfect

I Think is perfect
 

I think is perfect
I think it' s perfect
I would say the second one is the correct one. But sometimes I ' ve seen some sentences with think without a subject.
Can anybody provide some examples and explanations.

I think it's perfect is the correct one.
It can't be "I think is perfect" cause the subject "it" is missing

I think she is (or she's) perfect (she = subject)
I think it is perfect (or it's) (it is the subject)

Think without a subject is when you are giving a command eg:
Think about it
Think like me

El inglés no tiene sujeto tácito.

English has many instances where the subject is omitted.


He went to see his friends.
- Thought so.

He left in the middle of the night.
- See what I mean?

Gone fishing.
Been there. Done that.

The imperative (command) form is seldom used with a singular subject.


But, perhaps you meant that we cannot omit the subject 'it' in English. While that is true in textbook English, it is glossed over in colloquial speech. We slaughter the language.

Shouldn't matter to me.
Didn't rain like they said it would. Wasn't likely to happen with clear skies for a week now.

I suggest you say, "I think it is perfect". Less chance for ambiguity.
