What's the difference between rudder and sieve?

Rudder


Definition:

  • (n.) A riddle or sieve.
  • (n.) The mechanical appliance by means of which a vessel is guided or steered when in motion. It is a broad and flat blade made of wood or iron, with a long shank, and is fastened in an upright position, usually by one edge, to the sternpost of the vessel in such a way that it can be turned from side to side in the water by means of a tiller, wheel, or other attachment.
  • (n.) Fig.: That which resembles a rudder as a guide or governor; that which guides or governs the course.

  • (17) The rating typically proves accurate, but, Rudder writes, “in the back of our minds, there’s always been the possibility: maybe it works just because we tell people it does.

Sieve


Definition:

  • (n.) A utensil for separating the finer and coarser parts of a pulverized or granulated substance from each other. It consist of a vessel, usually shallow, with the bottom perforated, or made of hair, wire, or the like, woven in meshes.
  • (n.) A kind of coarse basket.

Example Sentences:
