riddle - 5 Letter Word, Removing letters

Take away my first letter, and I still sound the same.
Take away my last letter, I still sound the same.
Even take away my letter in the middle, I will still sound the same.
I am a five letter word.

What am I?

Answer

This is an old one.

The answer is:

EMPTY

Because:

MPTY still sounds like EMPTY,

EMPT still sounds like EMPTY,
and EMTY still (sort of) sounds like EMPTY.

And, of course, you can

take all 3 away and M T is left.
