He gives orders all over the place (7)
I believe the answer is:
general
'he gives orders all over the place' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really see how this works, but
'he' could be 'gene' and 'gene' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for general that I've seen before include "Catholic" , "blanket" , "Opposite of private!" , "Not specialised, rank" , "Not specialised or limited" .)
