Vs

Study these 2 sentences:
I don’t think it is going to rain tomorrow.
I think it is not going to rain tomorrow.
*Both sentences are grammatically correct, and both basically mean the same.
Question: What is different between the two sentences?
Answer : Sudden thought
“I don’t think it is going to rain tomorrow”
= you’ve thought, for at least a little while, that it won’t rain.
( It is not a sudden thought)
“I don’t think you/it/etc. …” is used much more often in American English.
“I think it is not going to rain tomorrow”
= Suddenly, you are thinking it is not going to rain tomorrow.
*has more emphasis on “I think” than the other sentence.
When you start a sentence with “I think,” it usually is a sudden insight. ( Just now, you thought it. )
Ex: I don’t think I’m going to the party tonight.
= I’ve thought about it, and I don’t think I will go the party.
I think I’m not going to the party tonight.
= Just now, I’m thinking I’m not going to the party.
Ex: I don’t think she loves me.
= I thought about it, and I don’t think she loves me.
I think she doesn’t love me.
= Just now, I’m thinking she doesn’t love me.
