Wild little creature doctor employed always (5,4)
I believe the answer is:
mouse deer
'wild little creature' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'doctor employed always' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'employed' becomes 'used' ('use' can be a synonym of 'employ').
'always' becomes 'eer' (poetic way of saying ever).
'mo'+'used'+'eer'='MOUSE-DEER'
Can you help me to learn more?
(Other definitions for mouse deer that I've seen before include "Its beastly" , "Small tusked mammal" , "Emeer's duo (anag) -- tiny hornless ruminant" , "chevrotain" .)
