Smart Tips
Try adding 'or not' at the end. If it sounds natural, 'whether' is usually the better choice.
Always check your pronouns. 'Are you coming?' asked by John to me becomes 'if I was coming'.
Pronúncia
Falling Intonation
Unlike direct questions which often rise at the end, reported questions have falling intonation because they are grammatically statements.
Statement Fall
She asked if I liked it. ↘
Conveys that this is a piece of reported information, not a direct question.

Mnemônico
Remember 'I.F.' — Indirect Form. If it's indirect, the 'If' comes first, and the 'Form' is a statement.
Associação visual

Rhyme

Notas culturais
British speakers are slightly more likely to use 'whether' in semi-formal situations compared to American speakers, who favor 'if' more broadly.
In global academic English, 'whether' is used to maintain an objective, detached tone, avoiding the conditional 'if' which can sometimes imply a 'supposition' rather than a 'question'.
The word 'whether' comes from the Old English 'hwæther', which specifically meant 'which of two'.

Perguntas frequentes (8)
In most cases, they are interchangeable. However, `whether` is more formal and is required after prepositions and before infinitives.
If the reporting verb is in the past, backshifting is standard. However, if the situation is still true (e.g., 'He asked if I live in London'), you can sometimes keep the present tense.
No, 'if or not' is generally considered incorrect. Use `whether or not` or just `if` by itself.
Because those are question auxiliaries used for inversion. Since reported questions are statements, they don't need question auxiliaries.
No. 'Asked that' is used for requests (subjunctive), not for reporting questions. Use `asked if`.
Only if the main clause is a question, e.g., 'Can you tell me if he's coming?' If the main clause is a statement, use a period.
You can use `wonder`, `inquire`, `want to know`, `query`, or `question`.
Historically yes, but now it's used for any yes/no question, even if only one option is mentioned.

German verb placement rules are even stricter than English.

French 'si' elides to 's' before 'il' (s'il), whereas English 'if' never changes.
〜かどうか (~ka dou ka)
The marker comes at the end of the clause in Japanese, but at the beginning in English.
ما إذا (ma idha)
Arabic often maintains the question particle within the indirect structure.
是否 (shìfǒu)
Chinese has no tense backshifting, which is a major hurdle for learners.
