one that propels; especially : a device that consists of a central hub with radiating blades placed and twisted so that each forms part of a helical surface and that is used to propel a vehicle (as a ship or airplane)
I encountered this word from the following reading “The Tool”. It appear on the line said “Under the dizzying whirl of the scythe-like propellers……”. I now understand a propeller basically means the whirl device on a ship or airplane.
