His few faults one loudly broaches? (8)
I believe the answer is:
fishwife
'his few faults one loudly broaches?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'his few faults one loudly' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'his' is 'ish' which is located in the answer.
'few' could be 'i' and 'i' is present in the answer.
'loudly' could be 'f' (short for forte - 'loud' in music) and 'f' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fishwife that I've seen before include "A coarse scolding woman of piscine origin" , "Sole trader" , "Old lady" , "Loud-mouthed woman" , "noted for her coarse language?" .)
