of doubt?

Saima Siddiqui · Accepted Answer

To
identify whether the conjunction,
â€œifâ€, is used in case of
doubt/uncertainty or condition, one has to understand the context
of the sentence

For
example:

Doubt/uncertainty

1 I
have no idea if she is married

2 I
cannot say if it has stopped raining

Condition

1
If you had come yesterday, you too would have
received the gifts

2 My
mother would have cooked our favourite food if she
had a holiday
