Hasty and careless entry for cup goes adrift (11)

I believe the answer is:

perfunctory

'hasty and careless' is the definition.

'entry for cup goes adrift' is the wordplay.
'goes adrift' is an anagram indicator.
'entry'+'for'+'cup'='entryforcup'
'entryforcup' anagrammed gives 'PERFUNCTORY'.

(Other definitions for perfunctory that I've seen before include "Done as a formality only" , "Merely formal" , "Careless or cursory" , "Not thorough" , "Hasty and superficial" .)

I've seen this clue in The Times.
