Chat with carer about odd fellow (9)
I believe the answer is:
character
'odd fellow' is the definition.
(thesaurus)
'chat with carer about' is the wordplay.
'with' says to put letters next to each other.
'about' indicates an anagram.
'chat' put after 'carer' is 'carerchat'.
'carerchat' with letters rearranged gives 'CHARACTER'.
(Other definitions for character that I've seen before include "eccentric individual" , "Part" , "case" , "Amusing individual" , "I, for example" .)
