Please turn and slip away (6)
I believe the answer is:
elapse
'slip away' is the definition.
(synonyms)
'please turn' is the wordplay.
'turn' indicates anagramming the letters.
'please' is an anagram of 'ELAPSE'.
'and' acts as a link.
(Other definitions for elapse that I've seen before include "'Pass by, as time (6)'" , "Pass away - asleep (anag)" , "Go past" , "Tick by" , "Go by - pass away" .)
