WILL-MIGHT FOR PREDICTIONS

English grammar: Will, might

We can use "will", "might" to make predictions in English. We often do this when we talk about the weather, for example.

Will and might

Both "will" and "might" are modal auxiliary verbs. This means that they are followed by the infinitive of the verb without "to":

"It will rain later." (Not "it will to rain…")
"It might rain later."

(For more information on how to use modal auxiliary verbs, see our page on can.)

We use "will" when we are sure that something will happen.
"It will be sunny later." (100% probability)

We use "might" when something is less sure.
"It might rain later. Take an umbrella with you." (50% probability)

The negative forms are:

"It won't…"
"It won't snow until December."

"It might not…"
"It might not be sunny at the beach."
