'Ore' is a rock or mineral containing metal that can be extracted; 'oar' is the paddle used to row a boat.
Noun. A rock or mineral from which a metal or valuable mineral can be profitably extracted.
The mine extracts copper ore from a depth of eight hundred metres.
Iron ore is the primary raw material used in the production of steel.
The region sits on enormous deposits of gold ore that remain largely unmined.
Noun. A long pole with a flat blade used to row a boat, resting on a pivot point at the side of the vessel.
She pulled on the oar and the boat glided smoothly towards the opposite bank.
One oar snapped in the rough current, leaving them to paddle with the remaining one.
The racing crew moved all eight oars in perfect synchrony.
Common mistake
"They rowed with wooden ores" when meaning the rowing paddles (correct: oars). Or "Gold ore paddles" (a mix-up of the two words). These are confused mainly in writing; they sound identical.
Trick to remember it
'Ore' has ORE like 'core' — things inside the earth. 'Oar' has OAR like 'soar' — things that move through open space (the oar moves through water as a bird soars through air).
Quick rule
Is it the rock from which metal is extracted? 'Ore'. Is it the paddle used to row? 'Oar'.
Did you know?
Iron ore is the most extracted mineral on Earth — over 2.5 billion tonnes per year. Steel (made from iron ore) underpins every skyscraper, bridge, ship, and railway. An oar is a Class 2 lever: the pivot point (the oarlock) sits between the effort (the rower's hands) and the load (water resistance). The Oxford-Cambridge Boat Race has been held annually since 1829 on the Thames — one of the oldest sporting events in the world. 'Ore' comes from Old English 'ar' meaning crude metal or bronze.
Exercise 1 · Pick the right one
The company ships iron _____ by cargo vessel to processing plants on the coast.
Exercise 2 · Pick the right one
She gripped the _____ tightly as the current pushed the boat towards the rocks.
Exercise 3 · Form the word
Is it the rock from which metal is extracted? 'Ore'. Is it the paddle used to row? 'Oar'.
