The province of little men (5)
I believe the answer is:
natal
'the province' is the definition.
(I have seen 'old province' mean 'natal' so perhaps 'province' could also mean 'natal')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for natal that I've seen before include "description of delivery" , "Brazilian port" , "Pertaining to birth" , "Connected to birth" , "Former African place" .)
