Twist-in-the-tail Masefield work describing love bird (8)
I believe the answer is:
cargoose
'twist-in-the-tail masefield' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'work describing love bird' is the wordplay.
'work' becomes 'care' (care is a kind of work).
'describing' means one lot of letters goes inside another (describe can mean to form the outline of).
'love bird' becomes 'goos' (I can't explain this - if you can you should give a lot more credence to this answer).
'care' placed around 'goos' is 'CARGOOSE'.
Can you help me to learn more?
(Another definition for cargoose that I've seen is " Crested grebe".)
