Paradise endlessly provides lift (5)
I believe the answer is:
heave
'lift' is the definition.
(I know that lift is a more specific form of heave)
'paradise endlessly' is the wordplay.
'paradise' becomes 'heaven' (synonyms).
'endlessly' means to remove the last letter.
'heaven' with its last letter taken off is 'HEAVE'.
'provides' acts as a link.
(Other definitions for heave that I've seen before include "Drag" , "Tug-of-war cry" , "Tug-of-war shout" , "Express" , "Pull hard; (sea) swell" .)
