Takes off part of the weekend, given flowers (9)
I believe the answer is:
satirises
'takes off' is the definition.
(take off can mean to mock or satirise)
'part of the weekend given flowers' is the wordplay.
'part of the weekend' becomes 'sat' (abbreviation for Saturday).
'given' means one lot of letters go next to another.
'flowers' becomes 'irises' (type of flower).
'sat'+'irises'='SATIRISES'
(Other definitions for satirises that I've seen before include "Makes exaggerated attacks" , "Makes fun of" , "Sends up" , "Ridicules" .)
