Does he get put on? (3)
I believe the answer is:
don
This clue could be a double definition.
'does he get' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'put on?' is the second definition.
(as in donning or putting on an item of clothing)
Can you help me to learn more?
(Other definitions for don that I've seen before include "A mafia chief or Spanish lord" , "Spaniard in a University?" , "Nod off like Mafia chief" , "Put on the learned man" , "A Spanish grandee like Quixote" .)
