Promoter


Definition:

  • (n.) One who, or that which, forwards, advances, or promotes; an encourager; as, a promoter of charity or philosophy.
  • (n.) Specifically, one who sets on foot, and takes the preliminary steps in, a scheme for the organization of a corporation, a joint-stock company, or the like.
  • (n.) One who excites; as, a promoter of sedition.
  • (n.) An informer; a makebate.

Example Sentences:
