Hind. khan(n)a, a house or room, which is also found in combs., e.g. buggy-khanna (coach house) or bottle-khanna (drinking house); Hotten (1867) attributes it to ‘Gypsey and Oriental’ and notes that ‘all slang and cant words which end in -ken are partly of Gypsey origin’ on which basis Partridge (1984) opts for a root in Rom. tan, a place; the term vanished from sl. c.1860, but has survived in costermonger jargon]
