Work on New Year list and act as host (2,3,7)
I believe the answer is:
do the honours
'host' is the definition.
(I've seen this before)
'work on new year list and act' is the wordplay.
I cannot really see how this works, but
'work' could be 'do' (synonyms) and 'do' is present in the answer.
'on' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'as' acts as a link.
Can you help me to learn more?
(Other definitions for do the honours that I've seen before include "Play host" , "Act as host or hostess" , "Serve as host" , "at a royal investiture, perhaps?" , "Perform a social duty for guests" .)
