Man, for example, insulted regularly (4)
I believe the answer is:
isle
'man for example' is the definition.
(Isle of Man is an example)
'insulted regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'insulted' are 'ISLE'.
(Other definitions for isle that I've seen before include "Eg, Staffa" , "one ringed in the main?" , "Capri for one" , "See 10 Down" , "''There is an ..., a bonny ...'' (anthem of Shannon RFC)" .)
