Chore getting butter at last into frying-pan (4)
I believe the answer is:
work
'chore' is the definition.
(thesaurus)
'butter at last into frying-pan' is the wordplay.
'at last' says to take the final letters.
'into' indicates putting letters inside.
'frying pan' becomes 'wok' (a pan for frying in).
The last letter of 'butter' is 'r'.
'r' placed inside 'wok' is 'WORK'.
'getting' is the link.
(Other definitions for work that I've seen before include "Wildly happy" , "Earn a living" , "Function; have a job" , "Labour" , "Put in effort" .)
