Some people claim that the true sense of the adjective verbal is ‘of or concerned with words’, whether spoken or written (as in verbal abuse), and that it should not be used to mean ‘spoken rather than written’ (as in a verbal agreement). For this meaning it is said that the adjective oral should be used instead. In practice, however, verbal is well established in this sense and in certain idiomatic phrases (such as a verbal agreement) cannot be simply replaced by oral.
