What is the difference between 'if' and 'as long as' in conditional clauses?

The difference between 'if' and 'as long as' in conditional clauses lies in the level of certainty and the conditions they express.

'If' is used to express a condition that may or may not be fulfilled. It indicates a possibility or uncertainty about the outcome. For example:
- If it rains, we will stay indoors. (There is a possibility of rain, but it may or may not happen.)

'As long as' is used to express a condition that is necessary for a particular outcome to occur. It implies a certain level of certainty and indicates that the condition must be fulfilled for the desired result. For example:
- You can borrow my car as long as you return it by 6 pm. (Returning the car by 6 pm is a necessary condition for borrowing it.)

In summary, 'if' expresses a possibility or uncertainty, while 'as long as' expresses a necessary condition for a specific outcome.
