Man perhaps read aloud passage (4)
I believe the answer is:
isle
'man perhaps' is the definition.
(Isle of Man is an example)
'aloud passage' is the wordplay.
'aloud' indicates a 'sounds like' (homophone) clue.
'passage' becomes 'aisle' (aisle can mean a path or passageway).
'aisle' sounds like 'ISLE'.
'read' acts as a link.
(Other definitions for isle that I've seen before include "Dogs, perhaps" , "eg Skye" , "Land encircled by water" , "Eg, Staffa" , "Land amid water" .)
