Grammar Point if / whetherif / whetherTopics Preferences and decisionsb1- Both if and whether are used in reporting questions which expect ‘yes’ or ‘no’ as the answer: She asked if/whether I wanted a drink., although whether sounds more natural with particular verbs such as discuss, consider and decide. When a choice is offered between alternatives, if or whether can be used: We didn’t know if/whether we should write or phone. In this last type of sentence, whether is usually considered more formal and more suitable for written English.
