He transfers his charges from one bank to another (8)
I believe the answer is:
ferryman
'he transfers his charges from one bank to another' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he transfers his charges from one bank to another' is the wordplay.
I cannot really see how this works, but
'he' could be 'man' (I've seen this in another clue) and 'man' is present in the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
'another' could be 'r' (I've seen this in other clues) and 'r' is located in the answer.
The remaining letters 'fry' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for ferryman that I've seen before include "Transporter across water" , "Charon's occupation on the River Styx" , "eg Charon (on the Styx)" , "He rows people across a river, like Charon" , "One plying a short water crossing" .)
