Once an official tree-feller? (8)
I believe the answer is:
alderman
'once an official' is the definition.
'alderman' can be an answer for 'official' (I've seen this before). I'm not sure about the 'once an' bit.
'tree-feller?' is the wordplay.
'tree' becomes 'alder' (alder is a kind of tree).
'feller?' becomes 'man' (I've seen this in another clue).
'alder'+'man'='ALDERMAN'
Can you help me to learn more?
(Other definitions for alderman that I've seen before include "Member of an English city council" , "Former civic dignitary" , "Member of English county council" , "superior member of county council" , "Old municipal official" .)
