Right inside without feeling fear (5)
I believe the answer is:
dread
'fear' is the definition.
(I know that fear can be written as dread)
'right inside without feeling' is the wordplay.
'right' becomes 'r' (common abbreviation).
'inside' is an insertion indicator.
'without feeling' becomes 'dead' (I've seen this in another clue).
'r' put within 'dead' is 'DREAD'.
(Other definitions for dread that I've seen before include "Fearful expectation" , "Affright" , "Great fear or apprehension" , "Show horror" , "Hairstyle" .)
