Reversed a limit on the French animal (6)
I believe the answer is:
alpaca
'animal' is the definition.
(South American animal)
'reversed a limit on the french' is the wordplay.
'reversed' says the letters should be written in reverse.
'limit' becomes 'cap' (capping is a kind of limiting).
'on' is a charade indicator (letters next to each other).
'the french' becomes 'la' (one of the French words for 'the').
'a'+'cap'+'la'='acapla'
'acapla' reversed gives 'ALPACA'.
(Other definitions for alpaca that I've seen before include "Cloth made from wool of S American llama" , "Long-haired mammal related to the llama" , "woolly character?" , "S American mammal related to the llama" , "Llama's relative" .)
