No longer existing — dead etc., in other words without pleasure (7)
I believe the answer is:
defunct
'no longer existing' is the definition.
(I've seen this before)
'dead etc in other words without pleasure' is the wordplay.
'dead' becomes 'd'.
'in other words' indicates anagramming the letters.
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'pleasure' becomes 'fun' (I've seen this in other clues).
'etc' is an anagram of 'ect'.
'ect' placed around 'fun' is 'efunct'.
'd'+'efunct'='DEFUNCT'
(Other definitions for defunct that I've seen before include "'No longer in force, inactive (7)'" , "Extinct" , "Dead or finished" , "dead and gone" , "Inoperative" .)
