Conditional Sentence

1.     Definition of Conditional Sentence
Conditional is a traditional label for the modal auxiliary verbs would and should when they do not express obligation. The name is given because sentences with these auxiliary verbs often imply an unstated condition.
For example, the sentence: “I would like a drink” appears to imply something like: “If I had a choice”.In practice, however, it is merely a polite way of asking for a drink. Conditional sentencesAny sentence of the form if...(then) is a conditional sentence.
