Newguest  +  428279 Sun, 07 Oct 07 07:30 PM Hi Are these two words always interchangeable? 1. I wonder if they will ever do it. 2. I wonder whether they will ever do it. thanks Newguest Joined on Sun, Feb 25 2007 Senior Member 2,098

If it is sunny tomorrow, we are going to go on a picnic. The word 'whether' suggests 'or not'.

	Yankee  +  428289 Sun, 07 Oct 07 07:54 PM Hi Doll I understood Newguest's question to be whether the words 'if' and 'whether' are always interchangeable.  And my response to that was that they are not.  My examples were of conditional sentences in which you cannot exchange 'whether' for 'if'.  Here is another sentence: Whether or not it is sunny tomorrow, we are going to go on a picnic. I don't think it likely that someone would try to use 'if' instead of 'whether' in that sentence.  You could possibly rephrase that last example this way: Even if the weather is not sunny tomorrow, we are going to go on a picnic. However, that is not just a simple exchange of two words. Yankee Conditionals
