Pleading for Quarex? (6)
I believe the answer is:
asking
'pleading' is the definition.
(to plead is to ask for something)
I don't understand how the rest of the clue works.
(Other definitions for asking that I've seen before include "Inquiring" , "For the ___; freely available" , "Presenting petition" , "Making request" , "Demanding" .)
