Weird out E. Grout, Esq (9)
I believe the answer is:
grotesque
'weird' is the definition.
(I've seen this before)
'out e grout esq' is the wordplay.
'out' indicates an anagram.
'e'+'grout'+'esq'='egroutesq'
'egroutesq' with letters rearranged gives 'GROTESQUE'.
(Other definitions for grotesque that I've seen before include "Bizarre and disfigured - preposterous" , "Fantastically hideous" , "Outlandish" , "Bizarre; monstrous" , "Horribly distorted" .)
