Complete electricity, gas or water supply for territory? (6)
I believe the answer is:
domain
'for territory?' is the definition.
(I've seen this before)
'complete electricity gas or water' is the wordplay.
I cannot really understand how this works, but
'complete' could be 'do' (doing is a kind of completing) and 'do' is located in the answer.
'gas' could be 'n' (chemical symbol for nitrogen) and 'n' is found within the answer.
The remaining letters 'mai' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'supply' is the link.
Can you help me to learn more?
(Other definitions for domain that I've seen before include "Sphere or territory" , "estate" , "Range of influence or field of activity" , "Scope of knowledge - owned land" , "Field of thought or activity" .)
