Deer has courage reportedly (4)
I believe the answer is:
hart
'deer' is the definition.
(hart is a kind of deer)
'courage reportedly' is the wordplay.
'courage' becomes 'heart' (heart is a kind of courage).
'reportedly' indicates a 'sounds like' (homophone) clue.
'heart' is a homophone of 'HART'.
'has' is the link.
(Other definitions for hart that I've seen before include "Adult male red deer" , "Male red-deer" , "Male deer; Rodgers collaborator" , "Richard Rodgers and Lorenz . . . . were famous musical partnership" , "Deer; Lorenz --, lyricist" .)
