Propagation


Definition:

  • (n.) The act of propagating; continuance or multiplication of the kind by generation or successive production; as, the propagation of animals or plants.
  • (n.) The spreading abroad, or extension, of anything; diffusion; dissemination; as, the propagation of sound; the propagation of the gospel.

Example Sentences:
