Failed to answer what some eat for breakfast before rising? (6)
I believe the answer is:
begged
'failed to answer' is the definition.
(as in 'begging the question')
'what some eat for breakfast before rising?' is the wordplay.
I cannot quite see how this works, but
'what some eat for breakfast' could be 'egg' and 'egg' is found within the answer.
The remaining letters 'bed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
(Other definitions for begged that I've seen before include "asked for money" , "Entreated" , "Beseeched" , "Pleaded for money" , "Asked for alms" .)
