A South American weasel - it's in the dictionary at the back (5)

Ross

I believe the answer is:

tayra

'a south american weasel' is the definition.

'in the dictionary at the back' is the wordplay.
'in' indicates the answer is hidden within the clue.
'back' says the letters should be written in reverse.
'aryat' is hidden within 'dictionary at the'.
'aryat' backwards is 'TAYRA'.

'it's' is the link.

(Another definition for tayra that I've seen is " weasel".)

I've seen this clue in The Guardian.
