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?
This is an old one.
The answer is:
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.
A postman, because he/she will be a postman without any letters.
Remove the first : isle
Remove the last : aisl
Remove the middle : aile
(Obviously assuming s remains silent even after removing the first/last)
