A hundred doubts and fears were pressing upon him, and—the second bell rang.

In this resolution he had begun to dress, but before he had finished had begun to have his doubts.

While in doubts as to his future he chanced to see the telegraph, and that decided him.

This, they think, (and justly think,) must fill me with doubts.

"Entirely," Edward answered, smiling at Mr. Burrows' doubts.

He felt a measure of relief because all doubts were gone now.

I don't believe a man can ever shake it off in this world: if he can in any other, I have my doubts.

You can set these doubts at rest, I think, if you will really help me to discover the truth.

Even the fact that her grief was a thing to be indulged or denied at will brought her no doubts.


early 13c., "to dread, fear," from Old French doter "doubt, be doubtful; be afraid," from Latin dubitare "to doubt, question, hesitate, waver in opinion" (related to dubius "uncertain;" see dubious), originally "to have to choose between two things."

The sense of "fear" developed in Old French and was passed on to English. Meaning "to be uncertain" is attested in English from c.1300. The -b- was restored 14c. by scribes in imitation of Latin. Replaced Old English tweogan (noun twynung), from tweon "two," on notion of "of two minds" or the choice of two implied in Latin dubitare (cf. German Zweifel "doubt," from zwei "two").
