What is meaning of wear out

[dharanija35]

I want to know the meaning of wear out, and also the meaning of exhausted. what is the difference between wearing out and exhausted.

They have much the same meaning, though 'wear out' can also mean to use something until it no longer works properly- if you wear shoes until they get holes in them, you wear them out.

There's also another meaning of "exhaust" that has nothing to do with wearing out: it means to use up completely:
"There was nothing else to do. They had exhausted all the other possibilities."
