Coarse description of some wines by a learner (6)
I believe the answer is:
brutal
'coarse' is the definition.
(thesaurus)
'description of some wines by a learner' is the wordplay.
'description of some wines' becomes 'brut' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'by' says to put letters next to each other.
'learner' becomes 'l'.
'brut'+'a'+'l'='BRUTAL'
Can you help me to learn more?
(Other definitions for brutal that I've seen before include "Callous" , "Cruel, in animal fashion" , "Cruel and unfeeling like an animal" , "Rough and cruel" , "Disposed to inflict pain" .)
