Old chap eating sprouts before Mass. He'll get complaints (9)
I believe the answer is:
ombudsman
'old chap eating sprouts before mass he'll get complaints' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'sprouts before mass he'll get complaints' is the wordplay.
I cannot quite understand how this works, but
'sprouts' could be 'buds' (bud is a kind of sprout) and 'buds' is found within the answer.
'mass' could be 'm' (symbol used in Physics e.g. f=ma) and 'm' is found within the answer.
The remaining letters 'oman' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ombudsman that I've seen before include "Public official" , "Commisioner" , "Official investigating complaints of maladministration" , "Government appointee who investigates complaints" , "Parliamentary commissioner" .)
