- A long-handled, paddled implement for rowing (sometimes steering) a boat with.
Probably earlier than the 15th century. From Old Norse and Anglo-Saxon, ar; later Middle English, ore.
Doesn’t require much introduction. It has a long handle going through an oarlock and a flat-bladed end which goes into the water. Oars are known to power rowboats, rafts, gondolas, and ancient galleys. They can also be used as steering devices, acting as a sort of rudder.
