Might vs. Will: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 12, 2023
'Might' implies possibility or potential, suggesting something could happen but isn't certain. 'Will' indicates a definite intention or future occurrence, showing certainty or commitment.

Key Differences

'Might' is used to express a possibility or probability, often implying uncertainty or speculation. In contrast, 'will' is used to express certainty or a strong intention, showing a clear commitment to future action.
In terms of likelihood, 'might' suggests a lower degree of certainty compared to 'will,' which indicates a high degree of certainty or inevitability.
'Might' is often used in conditional sentences to speculate about potential outcomes or situations. On the other hand, 'will' is used to make definitive statements about future events or actions.
'Might' can also indicate a polite suggestion or a less forceful option, whereas 'will' often conveys a decision or a promise.
In questions, 'might' can imply a gentle inquiry or request, whereas 'will' is used for more direct or assured questions.
