He can order everybody about (7)
I believe the answer is:
general
'he can order everybody about' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he can order everybody about' is the wordplay.
I cannot really understand how this works, but
'he' could be 'gene' and 'gene' is present in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is present in 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 "Officer of the highest rank" , "Normal; military rank" , "Officer < sweeping < public" , "Common - army officer" , "High ranking officer" .)
