Okay.

Atleast let me know what the hashes u created will do

They will encapsulate data, that is, they will associate keys with a value, $word with a $count

and what the foreach is intended for

foreach is just like for, it is a loop, it is intended for iterating, in this case over a list of keys

I can understand little bit. But not fully. Just explain me. I will try it

What do you understand?

You use "keys in a hash" in the title, you use two hashes, you use a loop , you recognize i5513 uses two hashes, where is the disconnect?
