: While I'm on the subject of superfluous words, why is it necessary (or is it in fact necessary), to add 'or not' when using the word 'whether'.

: Obviously when the condition involves more than 2 choices it's necessary to specify the condition, eg. whether to drive or catch a train (if there are other modes of transport available), but if it's simply a yes or no condition, then sure simply 'whether to catch a train' is sufficient, instead of 'whether or not to catch a train'. This is probably a lousy example, but I'm sure you've got the general idea.

It's a good question. The conjunction "whether" has several related meanings:

1) To introduce a single possibility - "I should find out whether he went to work today." This is almost exactly synonymous with "if", but may have a fractionally more doubtful connotation.

2) To introduce several possibilities - "Whether I sink or (whether I) swim, I'm still taking that new position." "Whether... or" is effectively synonymous here with "no matter if... or".

3) To mean either - "Whether by luck or (whether by) judgement, I backed the winning horse."

I think therefore that when the speaker/writer wants to highlight the fact that there are just two alternatives - black and white, or positive and negative, if you like - then "whether or not" is correct, as per the following example:

I'll be in the office tomorrow, whether I'm ill or not.
