One forming sort of corona round Crockett's head? (7)
I believe the answer is:
raccoon
'one' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'sort of corona round crockett's head?' is the wordplay.
'sort of' is an anagram indicator.
'round' means one lot of letters goes inside another.
'head?' says to take the initial letters (I've seen 'heads of' mean this).
The initial letter of 'crocketts' is 'c'.
'corona' with letters rearranged gives 'racoon'.
'racoon' placed around 'c' is 'RACCOON'.
'forming' is the link.
Can you help me to learn more?
(Other definitions for raccoon that I've seen before include "Mammal with pointed muzzle and long tail" , "Arboreal mammal" , "Furry American mammal" , "Omnivorous nocturnal mammal native to N and C America" , "Smallish American animal" .)
