the conjunction form of the word 'whether' serves to connect sentences or phrases. It is used to denote a choice between two alternatives or opinions, and can be used to introduce two clauses in a sentence.
1. I am considering whether to stay in my current job or to pursue another opportunity.
2. He was unsure whether to put more money into the stock market or to save it in a savings account.
3. We must decide whether we should take the risk or play it safe.
Be mindful of the word 'or' when using 'whether' as a conjunction; if the choice is between two characterizations, 'whether' can be used, but if the choice is between two distinct possibilities, the word 'or' must be used.
