Consider these two example sentences:

I don't think Kelly will pass the exam.


Kelly will not pass the exam.

Is it absolutely the same meaning or not if someone says these phrases?

Saying the second one means you are sure that Kelly won’t pass. The first one is just you having a thought of her failing the test (based on some evidence).

But also focus on their pitch as well, pitches can change the meaning of phrases.

Ex: “I don’t think Kelly will pass the exam” said in a low and nervous voice pitch, means you are only having a thought or a fear that she might fail the test. But saying the same sentence with a high and confident pitch will make the listeners think that you already know Kelly is going to fail.


No, Both the sentence are different. Your first sentence sounds to be a future prediction while the second sentence is your belief( i.e. you have proof for your statement )

  • You have got them backwards. "will" is a confident future prediction. "think" is used for a belief. A belief doesn't need any proof.
