Man perhaps in silver, oddly (4)
I believe the answer is:
isle
'man perhaps' is the definition.
(I've seen this before)
'in silver oddly' is the wordplay.
'oddly' indicates alternate letters.
'in'+'silver'='insilver'
The alternate letters of 'insilver' are 'ISLE'.
(Other definitions for isle that I've seen before include "Ait" , "Christmas or Easter, perhaps" , "Hawaii, perhaps" , "See 10 Down" , "Small area of land in water" .)
