Hawking maybe succeeded, since tit's injured (9)
I believe the answer is:
scientist
'hawking maybe' is the definition.
(Stephen Hawking is an example)
'succeeded since tit's injured' is the wordplay.
'succeeded' becomes 's' (genealogical abbreviation).
'injured' indicates anagramming the letters.
'since'+'tit'='sincetit'
'sincetit' is an anagram of 'cientist'.
's'+'cientist'='SCIENTIST'
(Other definitions for scientist that I've seen before include "`Tis nicest kind of specialist" , "Researcher - boffin" , "It's insect, strangely, this learned person knows about" , "Chemist or physicist, for instance" , "One studying nature or physics, say" .)
