Peep


Definition:

  • (v. i.) To cry, as a chicken hatching or newly hatched; to chirp; to cheep.
  • (v. i.) To begin to appear; to look forth from concealment; to make the first appearance.
  • (v. i.) To look cautiously or slyly; to peer, as through a crevice; to pry.
  • (n.) The cry of a young chicken; a chirp.
  • (n.) First outlook or appearance.

Example Sentences:
