If you think something is possible in the future, you are making a prediction.
I think England will win the next World Cup.
These are the most common expressions for making predictions. The percentages (%) are very approximate - just to show you the order of the expressions.
|It'll definitely rain.||100% chance of rain|
|It'll almost certainly rain. |
It's bound to rain.
|It'll probably rain. |
It's likely to rain.
|It'll possibly rain. |
It might rain.
|It might not rain.||20%-50%|
|It probably won't rain. |
It isn't likely to rain.
|It almost certainly won't rain.||1%-5%|
|It definitely won't rain.||0% chance of rain|
Notice the position of words like "definitely" - before "won't", but after "will".
We often use 'be going to' instead of 'will' for predictions. There usually isn't a difference, but 'be going to' can mean that we have a reason for making the prediction.
I think it'll snow next Christmas.
(but that's in 12 months - I can't know this)
I think it 's going to snow again tomorrow.
(there are a lot of clouds and the weather is very, very cold)
