Sewage collector lost his head in Sophocles play (8)
I believe the answer is:
cesspool
This clue might be a double definition.
'sewage collector' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'lost his head in sophocles play' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
Can you help me to learn more?
(Other definitions for cesspool that I've seen before include "Sump" , "Pit collecting filthy water" , "Covered pit where sewage is stored" , "Underground waste tank" , "Sink" .)
