Conditional tenses are used to speculate about:
– What could happen
– What we wish would happen.
– What might have happened
They have two clauses, an ‘if‘ clause and a main clause with ‘will‘ or ‘would‘. These two clauses are closely related.
If can also be substituted by ‘as soon as’ or ‘in case’
‘Will’ and ‘would’ can be substituted by other modal verbs such as ‘can’, ‘could’, ‘may’, ‘might’, ‘should’
There are 4 types of conditionals:
