Like ten to four on some watches (8)
I believe the answer is:
opposite
This could be a double definition.
'like ten' is the first definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'four on some watches' is the second definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'to' acts as a link.
(Other definitions for opposite that I've seen before include "reverse, in fact" , "Directly facing each other" , "Reverse or antithesis" , "Directly across from" , "Facing on the other side" .)
