Capricious little fellow starts eating large fish (3)
I believe the answer is:
elf
'capricious little fellow' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'starts eating large fish' is the wordplay.
'starts' indicates taking the first letters.
The initial letters of 'eating large fish' is 'ELF'.
Can you help me to learn more?
(Other definitions for elf that I've seen before include "Woodland sprite" , "Mischievous sprite" , "A leprechaun" , "One of the little folk" , "Santa's helper" .)
