CONTEST

The word contest has several interpretations within the English language. In popular parlance, a contest is often regarded as a conflict or competition. This may be friendly, such as a sports contest, or more aggressive such as a contention. Another interpretation of contest is in the form of a keen controversy, where one disputes an argument. Thus, one can contest another's statement.

Formerly, during the 17th century, the term contest was used to mean to bear witness, or to confirm or assert with the witness of an oath. Thus to contest was to swear to a fact or statement under oath. But this use had fallen into disuse by the 20th century.
