Turn end of satire into laconic humour (8)
I believe the answer is:
drollery
'humour' is the definition.
(I know that drollery is a type of fun)
'turn end of satire into laconic' is the wordplay.
'turn' becomes 'roll' (roll is a kind of turn).
'end of' indicates one should take the final letters.
'into' indicates putting letters inside.
'laconic' becomes 'dry'.
The final letter of 'satire' is 'e'.
'roll'+'e'='rolle'
'rolle' placed into 'dry' is 'DROLLERY'.
(Other definitions for drollery that I've seen before include "jokes" , "display of humour" , "comedy" , "Jesting" , "Comical quality" .)
