He stows away at the docks (9)
I believe the answer is:
stevedore
'he stows away at the docks' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really see how this works, but
'he' could be 'steve' and 'steve' is found within the answer.
The remaining letters 'dore' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stevedore that I've seen before include "One loads and unloads ships" , "One is employed at a dock to load and unload ships" , "Unloader of shipping vessels" , "dock pay for him?" , "Dock worker" .)
