Busy Conservative, a student said (9)
I believe the answer is:
cluttered
'busy' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'conservative a student said' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'a student' becomes 'L' (as in L-plates for learner drivers).
'said' becomes 'uttered' (I've seen this in another clue).
'c'+'l'+'uttered'='CLUTTERED'
Can you help me to learn more?
(Other definitions for cluttered that I've seen before include "Filled with things strewn about" , "Filled with objects in disorder" , "untidy" .)
