Hello, fellas. In this session we are going to discuss another form of conditional sentences. According to Betty Schrampfer Azar, a conditional sentence typically comprises of a conditional clause (an if-clause) as well as a result clause. However, the sentence can also be made without using if.

(More on conditional sentences: https://englishtips4u.com/2018/06/04/engclass-conditional-sentences-revisit/)

To omit if in a conditional sentence, make sure that the if-clause contains should, were, or had (past perfect). After if is omitted, the subject and verb of the if-clause are inverted.

Examples:

1. If you should need my help, please tell me.
   Should you need my help, please tell me.
2. If I were you, I would buy the book.
   Were I you, I would buy the book.
3. If they had prepared themselves better, they would have passed the test.
   Had they prepared themselves better, they would have passed the test.
