Time to get the better of one's better half (6)
I believe the answer is:
winter
'time' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Maybe there's a link between them I don't understand?
'get the better of one's better half' is the wordplay.
'get' says to put letters next to each other.
'the better of one' becomes 'win' (I can't explain this - if you can you should give a lot more credence to this answer).
'better half' becomes 'ter'.
'win' next to 'ter' is 'WINTER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for winter that I've seen before include "Coldest season" , "period of freeze?" , "'Now is the . . . . . . of our discontent' (Richard III)" , "Cold season" , "Time for mittens and scarves?" .)
