Misled about some land (4)
I believe the answer is:
isle
'land' is the definition.
(isle is a kind of land)
'misled about some' is the wordplay.
'some' indicates a hidden word.
'ISLE' is hidden within 'misled about'.
(Other definitions for isle that I've seen before include "like 'Hoy!'" , "Land encircled by water" , "Eg, Iona" , "Rum, for example" , "'This scepter'd - - (Shakespeare)" .)
