Like appeals close to Yuletide (6)
I believe the answer is:
please
'like' is the definition.
(pleasing is a kind of liking)
'appeals close to yuletide' is the wordplay.
'appeals' becomes 'pleas' (plea is a kind of appeal).
'close to' indicates one should take the final letters (the close/ending of).
The last letter of 'yuletide' is 'e'.
'pleas'+'e'='PLEASE'
(Other definitions for please that I've seen before include "Satisfy aesthetically" , "Gratify, make contented" , "See pal (anag) -- charm" , "Would you mind" , "Entertain" .)
