Man perhaps insulted from time to time (4)
I believe the answer is:
isle
'man perhaps' is the definition.
(Isle of Man is an example)
'insulted from time to time' is the wordplay.
'from time to time' indicates alternate letters (letters removed on a regular basis).
The alternating letters of 'insulted' are 'ISLE'.
(Other definitions for isle that I've seen before include "Christmas or Easter, perhaps" , "Little land" , "Ait" , "Eg, Staffa" , "Land amid water" .)
