Reconstituted rat's skin and tongue (8)

I believe the answer is:

sanskrit

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

'tongue' is the definition.
(Sanskrit is an example)

'reconstituted rat's skin' is the wordplay.
'rat's skin' anagrams to 'SANSKRIT'.
Though, I am not sure how the anagram is indicated.

'and' is the link.

Can you help me to learn more?

(Other definitions for sanskrit that I've seen before include "Ancient Indian language" , "Ancient language of Hindus in India" , "Ancient Hindu tongue" , "Ancient official language of India" , "Ancient Indo-European language" .)

I've seen this clue in The Everyman puzzle in The Observer.
