Tradesman with his own loo on the Underground (5)
I believe the answer is:
baker
This could be a double definition.
'tradesman' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'his own loo on the underground' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'with' is the link.
Can you help me to learn more?
(Other definitions for baker that I've seen before include "one with lots of dough" , "Bread-maker" , "Bread and cake maker" , "His 12 is13" , "Producer of bread/cakes" .)
