Endless palaver engulfing a second star (6)
I believe the answer is:
famous
'star' is the definition.
(thesaurus)
'endless palaver engulfing a second' is the wordplay.
'endless' means to remove the last letter.
'palaver' becomes 'fuss' (I've seen this before).
'engulfing' indicates putting letters inside.
'second' becomes 'mo' (both are short periods of time).
'fuss' with its final letter taken away is 'fus'.
'a'+'mo'='amo'
'fus' enclosing 'amo' is 'FAMOUS'.
(Other definitions for famous that I've seen before include "Well-known" , "Eminent" , "Well known" , "Known to very many people" , "Known-of widely" .)
