Promise to look after one's funeral? (9)
I believe the answer is:
undertake
'promise' is the definition.
(I know that promise is a is a more specific form of the action of undertake)
'look after one's funeral?' is the wordplay.
I cannot really understand how this works, but
'one' could be 'un' (northern English dialect form of 'one') and 'un' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for undertake that I've seen before include "Set about" , "Promise (to do a thing)" , "Promise - perform" , "Guarantee" , "Conduct funerals" .)
