What is an Adverb Clause of Condition?
An adverb clause of condition (also called a conditional clause) states the condition that is or would be necessary for specific actions talk about in the main clause to happen. When a sentence contains a conditional clause, it is called a conditional sentence.

Conditional Clauses in Adverb Clause of Condition
Some conditional clauses suggest that a situation is real – that is, the situation is true in the present, was true in the past, or may become true in the future. But some conditional clauses describe an unreal condition.
- If he comes, tell him we will be back in one hour. (Real Conditional)
- They wouldn’t have been so late if they had left home earlier.
(The situation describes by the conditional clause is unreal or imaginary)
Conditional clauses are divided into three types. Each type of conditional clause takes a different pair of sequences.
| Conditional Clause | Main Clause | Condition |
|---|---|---|
| If + Present Simple | Future Simple | Possible/Present likely condition |
| If + Past Simple (subjunctive) | Should/would | Present unlikely condition/improbable/hypothetical |
| If + Past Perfect | (Would, should, could, might) + have + past participle | Past condition/impossible/untrue |
