The fast animal Coe runs around a great deal (6)
I believe the answer is:
ocelot
'the fast animal' is the definition.
'ocelot' can be an answer for 'animal' (thesaurus). I am not certain of the 'the fast' bit.
'coe runs around a great deal' is the wordplay.
'runs around' indicates an anagram (I've seen 'running around' mean this).
'a great deal' becomes 'lot' (both can mean a large amount).
'coe' with letters rearranged gives 'oce'.
'oce'+'lot'='OCELOT'
Can you help me to learn more?
(Other definitions for ocelot that I've seen before include "Wild creature" , "American cat, like a small leopard" , "South and Central American wildcat" , "Yellow-black striped and spotted cat" , "Big cat" .)
