How to say "questionable" in Japanese
Choosing the right word
- 怪しいあやしいi-adjectiveThe broadest choice: covers suspicious people, dubious schemes, and anything that seems unreliable or shady. Use it when 'questionable' suggests you do not quite trust what you see.
- 疑わしいうたがわしいi-adjectiveUse for matters of doubt or uncertainty that can be judged or disputed — a doubtful claim, an uncertain outcome, a disputable conclusion. It weighs the evidence rather than the impression something gives.
- 怪しげあやしげna-adjective, nounA adjectival-noun form describing the suspicious look or air of something: a shady shop, a dubious manner. Use it when 'questionable' points to an outwardly fishy appearance rather than proven doubt.
- na-adjectiveUsually written in kana, this mainly means 'how' in polite questions; as 'questionable' it is limited to questioning the propriety or advisability of something. For most senses of 'questionable' it is not the word you want.
- i-adjectiveOnly matches 'questionable' through 'delicate (e.g. question)': it really means suggestive, risqué, or bordering on the obscene. Use it for off-colour content or a touchy question, not for doubt or suspicion.
For doubtful or suspect things use 「怪しい」 or 「疑わしい」 (evidence, claims, people); 「怪しげ」 describes a shady look or manner; 「いかが」 questions propriety; 「きわどい」 covers suggestive content or delicate questions.
