Man perhaps spreading lies (4)
I believe the answer is:
isle
'man perhaps' is the definition.
(Isle of Man is an example)
'spreading lies' is the wordplay.
'spreading' indicates an anagram.
'lies' with letters rearranged gives 'ISLE'.
(Other definitions for isle that I've seen before include "Small landmass" , "Sea-girt land" , "Body of land surrounded by water" , "eg Capri" , "Capri for one" .)
