dubious

/ˈdjuːbi.əs/adjective

Causing doubt; seeming unlikely to be true or honest.

Example sentences

  • “The website was full of dubious health advice with no sources.”
  • “I'm a bit dubious about his excuse for missing the meeting.”

Works two ways: a dubious claim invites doubt, while a person who is dubious feels it. 'Dubious honor' is an ironic set phrase.
