    think likelyverbtransitive
    To harbor a suspicion about someone or something, or to suspect that something is the case.
    I walk by the Rule of my Maſter, you walk by the rude working of your fancies. You are counted thieves already, by the Lord of the way; therefore, I doubt you will not be found true men at the end of the way.
    1678, John Bunyan, The Pilgrim’s Progress from This World

    Similarsuspect, fear

    Note

    In Scotland the verb still leans toward belief rather than away from it: "I doubt he's gone home" means "I suspect he has." Like I'm afraid, it usually introduces something unwelcome, as when Walter Scott has Bruce say "I doubt I have slain Comyn." Elsewhere it belongs to older prose such as Bunyan's. A modern reader can easily mistake it for the everyday "disbelieve" meaning, which is nearly its opposite.

Less common meanings

  1. 4
    class questionnounIndiacountable
    A question about something one has not fully understood, especially one put to a teacher for explanation.

    Before the exam, she emailed the professor with one last doubt about the reading list.

    He stayed back to clear his doubts before the exam.

    UsageCommon in have a doubt (about a topic) and clear or clarify one's doubts.

    Note

    Indian English gives the word a classroom meaning: a doubt is a question you bring to a teacher, not a misgiving you carry. "I have just one doubt, miss" asks for an explanation and casts no suspicion on anyone. Other varieties have dropped this use, so outside India "I have a doubt" can sound like distrust when only a question was meant.

  2. 5
    verbarchaictransitive
    To fear or dread something, especially to expect with dread that harm or misfortune is coming.
    Note

    The fearful side of the verb survives in older prose and verse. Its object is the danger itself: in a 1596 English translation of Commynes the horsemen "doubted the enimies sally," meaning they expected it and dreaded it, not that they questioned whether it would come. Scott's Lady of the Lake (1810) still has "doubt not aught from mine array."

  3. 6
    verbobsoletetransitive
    To fill a person with fear, so that they are frightened.
    Note

    Here the fear runs the other way: the subject frightens someone, and the frightened person is the object. In John Fletcher's Bonduca (c. 1613; published 1647), the valor of Caratach "more doubts me then all Britain," so it frightens the speaker more than the whole country does. It is the causative partner of the dreading sense.

Origin

Latin dubitāre ("to be uncertain, to hesitate") passed into Old French as douter and then into Middle English as douten, the source of the verb. Where dubitō itself came from is uncertain, but one theory connects it with dubius ("wavering, doubtful"), going back in the end to duo ("two"). Early modern spelling reformers put the b into the spelling to match the Latin, but English speakers have never pronounced it. The noun has the same Old French origin.
