Endless embrace causing troubles (5)
I believe the answer is:
cares
'troubles' is the definition.
(I've seen this in another clue)
'endless embrace' is the wordplay.
'endless' means to remove the last letter.
'embrace' becomes 'caress' (I've seen this before).
'caress' with its final letter taken off is 'CARES'.
'causing' acts as a link.
(Other definitions for cares that I've seen before include "Has concerns or interest" , "Minds" , "Worries, anxieties" , "Feels interest or concern" .)
