Joint covering end of ski lift (5)
I believe the answer is:
hoick
'lift' is the definition.
(thesaurus)
'joint covering end of ski' is the wordplay.
'joint' becomes 'hock' (hock is a kind of joint**).
'covering' means one lot of letters goes inside another.
'end of' indicates one should take the final letters.
The final letter of 'ski' is 'i'.
'hock' going around 'i' is 'HOICK'.
(Other definitions for hoick that I've seen before include "Lift sharply" , "Tug" , "Rise up" , "Pull abruptly" , "Lift abruptly" .)
