Artisan with his own dozen (5)
I believe the answer is:
baker
This could be a double definition.
'artisan' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'his own dozen' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for baker that I've seen before include "job" , "one who works in a hot place" , "Maker of cakes/bread" , "Producer of bread/cakes" , "His 12 is 13" .)
