Hay strewn around English animal (5)
I believe the answer is:
hyena
'animal' is the definition.
(I've seen this before)
'hay strewn around english' is the wordplay.
'strewn' indicates an anagram.
'around' is an insertion indicator.
'english' becomes 'en' (I can't explain this - if you can you should give a lot more credence to this answer).
'hay' is an anagram of 'hya'.
'hya' going around 'en' is 'HYENA'.
Can you help me to learn more?
(Other definitions for hyena that I've seen before include "African scavenger" , "Laughing mammal?" , "Dog-like carrion eater" , "Scavenging animal" , "Scavenging carnivore" .)
