Snicket in my native Lancashire - ginnel when I lived in Leeds - twitten down here in West Sussex.

Do "lokes" count? Many years in Norwich, in the Bere Street area, there were narrow passages of the street, and these opened out into central courtyards, often with workshops overlooking the yards. An elder brother of of one of my Suffolk great-grandparents had a coach works in one of these lokes in the late 19th century.

Any other places have lokes?
