Whig can be seen involved in an informal chat (7)

I believe the answer is:

chinwag

I'm a little stuck... Click here to teach me more about this clue!

'an informal chat' is the definition.
(chinwag means a chat)

'whig can be seen involved' is the wordplay.
'whig can' anagrams to 'CHINWAG'.
But, I'm not sure how this is indicated.

'in' is the link.

Can you help me to learn more?

(Other definitions for chinwag that I've seen before include "Gossip" , "Chat (colloq.)" , "Move mandible about in informal chat" , "Conversation (slang)" , "Yak" .)

I've seen this clue in The Globe and Mail.
