Chat show host maybe at breaks changing celebs (17)
I believe the answer is:
conversationalist
'chat show host maybe at breaks changing celebs' is the definition.
I can't tell whether this definition defines the answer.
'chat show host maybe' is the wordplay.
'chat' becomes 'conversation' (I've seen this before).
'show host maybe' becomes 'alist' (I can't justify this - if you can you should give a lot more credence to this answer).
'conversation'+'alist'='CONVERSATIONALIST'
Can you help me to learn more?
(Other definitions for conversationalist that I've seen before include "One good at chatting" , "Good chatter" , "One skilled in talking with others" , "One good at talking" .)
