What is the conditional sentence?
A conditional sentence is a type of sentence that states a condition and the outcome of that condition occurring. Conditional sentences are made up of a dependent clause and an independent clause joined to express said condition.
A conditional sentence contains an independent clause and a dependent clause that almost always begins with “if.” A conditional sentence is only a conditional sentence if it has both of these parts.
- If I save money. I can travel abroad for a vacation. (here in this sentence the dependent clause If I save money, but the independent clause I can travel abroad.)
- If you finish your homework early. You can watch T.V. (here in this sentence the dependent clause If you finish your homework early but the independent clause you can watch T.V.)
