Can "doubt" be used as a synonym of "question"? [duplicate]

Solution 1:

The word doubt can mean question in Indian English.

This usage comes from the days when England first colonized India; it is now archaic in the U.S. and the U.K., but is still widespread in India.

From the O.E.D.:

  1. A matter or point involved in uncertainty; a doubtful question; a difficulty. Obsolete.
