Cable company needing a vote in support (4)
I believe the answer is:
coax
'cable' is the definition.
(I know that coax is a type of cable)
'company needing a vote in support' is the wordplay.
'company' becomes 'co' (abbreviation).
'needing' is a charade indicator (letters next to each other).
'vote in' becomes 'x' (how votes are marked. I am not sure about the 'in' bit.).
'support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'co'+'a'+'x'='COAX'
Can you help me to learn more?
(Other definitions for coax that I've seen before include "lead not to get wires crossed?" , "Inveigle" , "Gradually persuade (someone)" , "Wheedle, persuade by flattery" , "sort of cable" .)
