What's the difference between channel and part?

Channel


Definition:

  • (n.) The hollow bed where a stream of water runs or may run.
  • (n.) The deeper part of a river, harbor, strait, etc., where the main current flows, or which affords the best and safest passage for vessels.
  • (n.) A strait, or narrow sea, between two portions of lands; as, the British Channel.

  • (n.) A gutter; a groove, as in a fluted column.
  • (n.) Flat ledges of heavy plank bolted edgewise to the outside of a vessel, to increase the spread of the shrouds and carry them clear of the bulwarks.
  • (v. t.) To form a channel in; to cut or wear a channel or channels in; to groove.
  • (v. t.) To course through or over, as in a channel.
