Confident elf's ears reshaped (8)
I believe the answer is:
fearless
'confident' is the definition.
(I've seen this before)
'elf's ears reshaped' is the wordplay.
'reshaped' is an anagram indicator.
'elfs'+'ears'='elfsears'
'elfsears' anagrammed gives 'FEARLESS'.
(Other definitions for fearless that I've seen before include "Totally courageous" , "game?" , "Not afraid" , "Hardy" , "Daring, brave" .)
