To roar out? That could suit me (6)
I believe the answer is:
orator
'could suit me' is the definition.
I can't tell whether this defines the answer.
'to roar out?' is the wordplay.
'out?' is an anagram indicator (out can mean wrong or inaccurate).
'to'+'roar'='toroar'
'toroar' is an anagram of 'ORATOR'.
'that' is the link.
(Other definitions for orator that I've seen before include "He lectures" , "Formal speech maker" , "Rhetorician" , "Eloquent type" , "he can talk" .)
