Result of endless personal belongings (6)
I believe the answer is:
effect
'result' is the definition.
(synonyms)
'endless personal belongings' is the wordplay.
'endless' means to remove the last letter.
'personal belongings' becomes 'effects' (I've seen this before).
'effects' with its final letter taken away is 'EFFECT'.
'of' is the link.
(Other definitions for effect that I've seen before include "Result; make happen" , "Change produced by action, result" , "Grounds for an act" , "Consequence of an action" , "Accomplish - result" .)
