Eastern fellow set about getting title (4)
I believe the answer is:
name
'title' is the definition.
(I've seen this before)
'eastern fellow set about' is the wordplay.
'eastern' becomes 'e'.
'fellow' becomes 'man' (I've seen this before).
'set about' is a reversal indicator.
'e'+'man'='eman'
'eman' backwards is 'NAME'.
'getting' acts as a link.
(Other definitions for name that I've seen before include "Famous person; identify" , "Call; reputation" , "Title; famous person" , "Good reputation; specify; christen" , "Designation; fame" .)
