Provided That vs. On Condition That

Provided that can be used as a conjunction. It is used to introduce a condition. It means something will happen only if another thing also happens.

• You can borrow my car, provided that you drive it carefully.
• You can watch TV provided that you finish your homework first.
• I will go provided that she invites me.
• I will take you there, provided that you pay me.
• You may go out provided that you are back by ten o’clock.

In clauses introduced by provided that, we use a present tense to refer to the future.

• I will accept the job provided that they offer me a good salary. (NOT I will accept the job provided that they will offer me a good salary.)

Usually, the same idea can be expressed using if or on condition that.

• You can watch TV on condition that you finish your homework first.
• If you finish your homework first, you can watch TV.
• If she invites me I will go.
• If you pay me, I will take you there. OR I will take you there on condition that you pay me.
• If they offer me a good salary, I will accept the job.
