Hang around unfinished toilet when working on River's Edge (6)
I believe the answer is:
loiter
'hang around' is the definition.
(I know that hang around can be written as loiter)
'unfinished toilet when working on river's edge' is the wordplay.
'unfinished' means to remove the last letter.
'toilet' becomes 'loo' (loo can informally mean a toilet).
'when working on river's edge' becomes 'iter' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'loo' with its last letter taken away is 'lo'.
'lo'+'iter'='LOITER'
Can you help me to learn more?
(Other definitions for loiter that I've seen before include "Hang about, with 25 dn perhaps" , "Dawdle, hang around" , "Linger, tarry" , "Hang around furtively" , "Tarry like toiler" .)
