Paddle or ore?

What’s the difference between a paddle and a ore (oar)?

You would use a paddle to propel yourself through water in a small boat.

Ore is a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted. I don't think it would be of much use for kayaking, unless you're selling it to buy one. ;)

Right how about a Oar. What’s the difference between a paddle and a oar?

a paddle you hold the entire thing and use your arms for leverage, whereas with an oar, you have it placed in a stirrup? and use that for leverage to row.

at least so think

What's the difference between a "paddle" and an "oar"? A paddle is usually 4' to 5' long and used with two hands, such as in a canoe or kayak (a kayak uses a double-ended paddle). An oar is usually 9' to 11' long and requires an oar lock (or fulcrum) so that it can act like a lever against the water such as in a rowboat or Viking ship. A person paddles with a paddle and rows with an oar.

Thank you.
