Yielding part of the debut due (6)
I believe the answer is:
bowing
'yielding' is the definition.
(bowing is a kind of yielding)
'part of the debut due' is the wordplay.
'part of the debut' becomes 'b' (I can't explain this - if you can you should believe this answer much more).
'due' becomes 'owing' ('owing' can be similar in meaning to 'due').
'b'+'owing'='BOWING'
Can you help me to learn more?
(Other definitions for bowing that I've seen before include "musical technique" , "deforming with age" , "Playing stringed instrument" , "Bending" , "Acknowledging applause" .)
