oar
(a pole with a flat blade at one end, used for rowing a boat)
- I took an oar and rowed the boat out to sea.
- We pulled hard on the oars until we reached to the shore.

(rock, earth, etc. from which you get metal)
- The ship was carrying a load of silver ore.
- They found a rich vein of iron ore in the hillside.
You help me very much, I’m so thankful.
