See saint getting confused (4)
I believe the answer is:
lost
'confused' is the definition.
('lost' can be a synonym of 'confused')
'see saint getting' is the wordplay.
'see' becomes 'lo' (archaic word meaning 'look!').
'saint' becomes 'st'.
'getting' means one lot of letters go next to another.
'lo'+'st'='LOST'
(Other definitions for lost that I've seen before include "Mislaid or astray" , "Unable to find one's way" , "Unable to be found" , "Baffled" , "Missing" .)
