Explain the concept of 'provided that' and 'providing' in conditional clauses and provide examples.

In conditional clauses, the phrases 'provided that' and 'providing' are used to introduce a condition that must be met in order for the main clause to occur. These phrases indicate that a particular action or situation is necessary for the outcome described in the main clause.

The phrase 'provided that' is commonly used to introduce a condition that must be fulfilled for something else to happen. It implies that if the condition is met, then the main clause will take place. Here are a few examples:

1. You can borrow my car provided that you return it by tomorrow.
- This sentence means that the person can borrow the car, but only if they return it by tomorrow.

2. We will go for a picnic provided that it doesn't rain.
- This sentence indicates that the picnic will happen, but only if it doesn't rain.

3. You can join the team provided that you pass the tryouts.
- This sentence states that the person can become a part of the team, but only if they pass the tryouts.

On the other hand, the phrase 'providing' is used in a similar way to 'provided that', but it is more commonly used in informal speech. It also introduces a condition that must be met for the main clause to occur. Here are a few examples:

1. You can come to the party, providing you bring a gift.
- This sentence means that the person can attend the party, but only if they bring a gift.

2. I will help you with your homework, providing you promise to study harder.
- This sentence indicates that the speaker will assist with homework, but only if the person promises to study harder.

3. You can use my computer, providing you don't download any unauthorized software.
- This sentence states that the person can utilize the computer, but only if they refrain from downloading unauthorized software.

In summary, both 'provided that' and 'providing' are used in conditional clauses to introduce a condition that must be fulfilled for the main clause to occur. They indicate that a particular action or situation is necessary for the desired outcome.
