Cursory (11)
I believe the answer is:
perfunctory
'cursory' is the definition.
(I know that cursory can be written as perfunctory)
This is the entire clue.
(Other definitions for perfunctory that I've seen before include "Not thorough" , "Careless or cursory" , "Hasty and superficial" , "Done with little effort" , "Merely formal" .)
