Telegraphing (entertainment)
Telegraphing, in the creation or performance of creative works, is conveying information to the audience through acting or nonverbal clues, providing a clear hint of the meaning or outcome of a dramatic action. Telegraphing may undercut suspense by advance disclosure or extreme hinting of an element in a composition, narrative plot, or recitation.
