Animal fur, for example, impressed at first (5)
I believe the answer is:
coati
'animal' is the definition.
(I've seen this before)
'fur for example impressed at first' is the wordplay.
'fur for example' becomes 'coat' (fur is a kind of coat).
'at first' says to take the initial letters.
The first letter of 'impressed' is 'i'.
'coat'+'i'='COATI'
(Other definitions for coati that I've seen before include "Furry animal" , "S. and Central American raccoon-like animal" , "South American animal" , "Plantigrade carnivore" , "beast" .)
