Unintelligent letter to an England cricketer (5)
I believe the answer is:
thick
'unintelligent' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'letter to an england cricketer' is the wordplay.
'letter' becomes 't'.
'to an england cricketer' becomes 'hick' (I can't explain this - if you can you should believe this answer much more).
't'+'hick'='THICK'
Can you help me to learn more?
(Other definitions for thick that I've seen before include "Stupid; (of voice) husky" , "Stupid; close-packed" , "Stupid (as two short planks?)" , "deficient in understanding" , "Friendly" .)
