Sends up flowers after end of week? (9)
I believe the answer is:
satirises
'sends up' is the definition.
(I've seen this before)
'flowers after end of week?' is the wordplay.
'flowers' becomes 'irises' (type of flower).
'after' says to put letters next to each other.
'end of week?' becomes 'sat' (I've seen this in other clues).
'irises' put after 'sat' is 'SATIRISES'.
(Other definitions for satirises that I've seen before include "Ridicules" , "Makes exaggerated attacks" , "Sends up" , "Makes fun of" .)
