Spline


Definition:

  • (n.) A rectangular piece fitting grooves like key seats in a hub and a shaft, so that while the one may slide endwise on the other, both must revolve together; a feather; also, sometimes, a groove to receive such a rectangular piece.
  • (n.) A long, flexble piece of wood sometimes used as a ruler.

Example Sentences:
