Argument on what young lady consumed (6)
I believe the answer is:
debate
'argument' is the definition.
(I know that argument can be written as debate)
'lady consumed' is the wordplay.
'lady' becomes 'deb' ().
'consumed' becomes 'ate' (to eat is to consume food).
'deb'+'ate'='DEBATE'
'on what young' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for debate that I've seen before include "Talk" , "Discussion with arguments for and against" , "Formal public discussion" , "Discuss formally" , "Discussion throung argument" .)
