Are his strategy and tactics all over the place? (7)
I believe the answer is:
general
'are his strategy and tactics 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.
'are his strategy and' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'are' is 'era' which is within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
The remaining letters 'gel' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for general that I've seen before include "Normal; military rank" , "Leader" , "Not specialised, like army chief" , "Opposite of private!" , "Senior military officer" .)
