He evidently has a following in the work force (7)
I believe the answer is:
foreman
'he evidently' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a following in the work force' is the wordplay.
'a following' means one lot of letters go next to another.
'in the' becomes 'ore' (I am not sure about this - if you are sure you should believe this answer much more).
'work' becomes 'man' (man can mean to work or operate (e.g.) a machine).
'force' becomes 'f' (symbol used in Physics e.g. f=ma).
'ore'+'man'='oreman'
'oreman' after 'f' is 'FOREMAN'.
'has' is the link.
Can you help me to learn more?
(Other definitions for foreman that I've seen before include "Charge hand" , "Supervising worker" , "Gaffer, boss" , "Male supervisor" , "spokesman" .)
