How to say "suspicion" in Japanese

Choosing the right word
  • 疑問ぎもんJLPT N3approx.Common
    noun, na-adjectiveCovers 'suspicion' only in the weak sense of a doubt or question about something, as in casting doubt on a claim. It is really 'doubt' or 'question', so it seldom expresses serious suspicion of wrongdoing.
    何なんか疑問ぎもんがあったら彼かれにお尋たずねください。↗
    Ask him if you have any doubt.
  • 容疑ようぎCommon
    noun, noun (suffix)The suspicion that someone has committed a specific crime, as held by police or prosecutors; it also means the charge itself. This is the word in contexts like arrest or investigation of a suspect.
    The official was suspected of accepting bribes from the construction companies.
  • 不審ふしんJLPT N1approx.Common
    noun, na-adjectiveSuspicion in the sense of mistrust or finding someone or something strange and dubious, such as suspicious behavior. It conveys wariness toward a person, action, or object rather than a formal accusation.
    A policeman was gazing at a suspicious pedestrian.
  • 疑念ぎねんCommon
    nounA doubt or misgiving that lingers in one's mind, a gnawing uncertainty about whether something is true or right. It is an internal feeling of suspicion rather than an outward accusation.
    案の定あんのじょう、彼かれは疑念ぎねんを抱いだいていた。↗
    Sure enough, he entertained doubts.
  • 嫌疑けんぎCommon
    nounLike 容疑, this is suspicion of criminal involvement, the suspicion directed at a suspect. It centers on the suspected person's implication in an offense rather than the charge as formally framed.
    彼かれに窃盗せっとうの嫌疑けんぎがかかっている。↗
    He is under suspicion of theft.

For legal suspicion of a crime use 容疑 or 嫌疑; for a personal feeling of doubt or mistrust choose 疑念, 不審, or 疑問, depending on whether it is a misgiving, wariness, or a question.
