Notice large worker's collared parish officer (6)
I believe the answer is:
beadle
'parish officer' is the definition.
(I've seen this before)
'notice large worker's collared' is the wordplay.
I cannot quite understand how this works, but
'notice' could be 'ad' and 'ad' is present in the answer.
'large' could be 'l' and 'l' is present in the answer.
'worker' could be 'bee' (I've seen this before) and 'bee' is found in the leftover letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beadle that I've seen before include "College officer" , "College official" , "Bumble's job (Oliver Twist)" , "Old parish officer" , "Old poorhouse official (eg Mr Bumble)" .)
