A vote to the other side? (6)
I believe the answer is:
across
'the other side?' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?
'a vote' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
The remaining letters 'cross' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for across that I've seen before include "From side to side, like this clue" , "ax" , "Transversely" , "...this is 'Number Ten'" , "To the opposite side" .)
