Lech Walesa's last letter hampers quiet youngster superficially (5)
I believe the answer is:
satyr
'lech' is the definition.
(I've seen this in another clue)
'walesa's last letter hampers quiet youngster superficially' is the wordplay.
I cannot quite see how this works, but
'last' could be 't' (I've seen this in other clues) and 't' is located in the answer.
'letter' could be 'y' (Y is a letter of the alphabet) and 'y' is present in the answer.
The remaining letters 'sar' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for satyr that I've seen before include "Trays (anag.)" , "Greek sylvan deity" , "Classical deity" , "Lustful Greek woodland god" , "Oversexed chap" .)
