One who finds cadging absorbing? (7)

I believe the answer is:

sponger

I'm a little stuck... Click here to teach me more about this clue!

'one who finds cadging' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'absorbing?' is the wordplay.
I cannot really understand how this works, but
'absorbing?' could be 'sponge' (I've seen this before) and 'sponge' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for sponger that I've seen before include "cleaner?" , "One living at others' expense" , "One who mooches" , "Person who lives at another's expense" , "Parasite" .)
