Regular staff, one looking after cattle (8)
I believe the answer is:
stockman
'regular' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'staff one looking after cattle' is the wordplay.
I cannot quite understand how this works, but
'staff' could be 'man' (as in staffing or manning a particular place) and 'man' is located in the answer.
'cattle' could be 'stock' (I've seen this before) and 'stock' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for stockman that I've seen is " Australian cowboy".)
