Sir Harry presumably gave praise freely (6)

Ross

I believe the answer is:

lauder

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

'sir harry' is the definition.
(I've seen this in another clue)

'presumably gave praise freely' is the wordplay.
I cannot really understand how this works, but
'praise' could be 'laud' (lauding is a kind of praising) and 'laud' is found in the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for lauder that I've seen before include "One celebrating" , "music-hall entertainer" , "Knighted Scottish music hall comedian" .)
