Daring fellow without sense of sound? (8)
I believe the answer is:
fearless
'daring' is the definition.
(I've seen this before)
'fellow without sense of sound?' is the wordplay.
'fellow' becomes 'les' (Les is a man's name).
'without' is an insertion indicator (some letters go outside or 'without' others).
'sense of sound?' becomes 'fears' (I am not sure about this - if you are sure you should believe this answer much more).
'les' put within 'fears' is 'FEARLESS'.
Can you help me to learn more?
(Other definitions for fearless that I've seen before include "Hardy" , "Extremely brave" , "Audacious" , "Not afraid" , "Bold" .)
