Adverb Clauses of Condition
These adverb clauses show that the ideas expressed in the result clause (or independent clause) are possible in certain circumstances. We use the subordinating conjunctions if, even if, only if, unless, whether or not, in case to express these conditions.

- If Luke Skywalker did not have the Force, he would not be able to use Jedi mind tricks.
- Unless Han Solo tells Princess Leia that he loves her, she will not wait for him after he is cryogenically frozen.
