Slander cricketer possessing unnatural ability? (9)
I believe the answer is:
bespatter
'slander' is the definition.
(thesaurus)
'cricketer possessing unnatural ability?' is the wordplay.
'cricketer' becomes 'batter' (someone batting).
'possessing' is an insertion indicator.
'unnatural ability?' becomes 'esp' (I can't justify this - if you can you should believe this answer much more).
'batter' enclosing 'esp' is 'BESPATTER'.
Can you help me to learn more?
(Other definitions for bespatter that I've seen before include "Defame" , "Make mess of" , "Spray with droplets" , "Dirty" .)
