Supporter of electricity? (5)
I believe the answer is:
pylon
This clue might be a double definition.
'supporter' is the first definition.
(I have seen 'A supporter' mean 'pylon' so perhaps 'supporter' could also mean 'pylon')
'electricity?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for pylon that I've seen before include "Electricity grid construction" , "Tower or tall post" , "power supplier?" , "Steel tower carrying power lines" , "Elec. cable tower" .)
