Etymology

It is inherited from Middle English duten, douten,[2][3] borrowed from Old French douter (“to doubt, be doubtful, be afraid”), doter,[3][2][4] from Latin dubitō (“I doubt, hesitate, waver in opinion”),[3][2] related to dubius “uncertain”, the source of dubious,[2][4] from duo “two”, with the sense “of two minds, undecided between two things”.[3] The noun is from Old French doute, from the verb.[2][3] The -b- was put back in French and English spelling by scribes in imitation of Latin,[3][4] as early as Gower (1393) and regularly from Thomas More (1513);[2] French dropped it again in the 17th century, but English kept it, though it was never pronounced.[3][5] The word replaced Old English twēogan, from twēo “two”.[3]

Earliest recorded meaning

“To fear, be afraid”, a sense now obsolete: probably before 1200, in the Ancrene Riwle,[2] about 1200;[3] the noun, “uncertainty”, is also from about 1200.[3][2]

Semantic evolution

The sense “fear” developed in Old French and passed into English.[3] The meaning “to be uncertain, waver in opinion” is attested from about 1300,[3][6] and the transitive “to be uncertain of the truth of, to distrust” from about 1300 too.[3] The noun's sense “fear, dread” (before 1225) is also obsolete.[6] A matter of uncertainty is a doubt from the late 14th century,[3] and no doubt, “certainly”, is from about 1400.[3] In Scots and northern English dialects I doubt still means “I fear, I suspect”.[7][8] Doubtless is from about 1380, in Chaucer, and doubtful from about 1395, in the Wycliffe Bible.[2] The first doubting Thomas was the apostle who would not believe Christ had risen until he had touched his wounds.[5]
