What is the use of each in the sentences? Are there any specific rules for their uses?

"I could get more work done if only there weren"t so much noise."

"We will manufacture these handbags only if we can obtain the right leather."



Consider the following three sentences:

If I had the money, I would get the operation.

Bạn đang xem: If and only if

If only I had the money, I would get the operation.I would get the operation only if I had the money.

The first expresses a simple failed conditional. I don"t have the money, but if I did, I would get the operation.

The second expresses a failed conditional with greater emotional content. I don"t have the money, but if I did, I would get the operation and it really bothers me.

The third expresses a failed conditional, without the emotional nội dung, but with a greater stress on the monetary constraint.

"Only if" và "if only" are idiomatic phrases that are quite different in meaning.

"If" is used lớn express a condition. When used after only i.e. only if, it expresses a strong condition or the only situation in which something can happen. A few examples of its use are given below:

1- I"ll come to the tiệc ngọt only if I can bring my frikết thúc with me.

2- you will get your payment only if you complete the work.

We use the phrase "if only" to lớn wish that something was true or something had happened. Please look at the following examples:

1- If only I were rich.
