Programme editor dropping duke in favour of knight's forebear (10)
I believe the answer is:
progenitor
'forebear' is the definition.
(I've seen this before)
'programme editor dropping duke in favour of knight's' is the wordplay.
I cannot really see how this works, but
'programme' could be 'prog' (short for programme) and 'prog' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
'knight' could be 'n' (chess abbreviation) and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for progenitor that I've seen before include "Ancestor" , "founder" , "dad" , "Forebear" , "Forefather" .)
