Reportedly steps over fence in dash (5)
I believe the answer is:
style
'dash' is the definition.
(synonyms)
'reportedly steps over fence' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'steps over fence' becomes 'stile' (I've seen this before).
'stile' sounds like 'STYLE'.
'in' acts as a link.
(Other definitions for style that I've seen before include "Elegance, sophistication" , "Showy way of life - elegance" , "Elan" , "Pointed pen" , "Manner or way of doing something" .)
