Polari
From our UK edition
Of the contribution to English that Polari is claimed to have brought, perhaps naff is the most current-sounding. An older suggestion for its origin, recorded in the Oxford English Dictionary, is from northern English naffu, ‘simpleton’. But, in a refreshing wander through the forest of Jonathon Green’s Dictionary of Slang, which this week went online, I ran into other possibilities. Not only does he record the suggestion that it came into Polari from 16th-century Italian, gnaffa, ‘a despicable person’, he also considers a Romany origin, from naflo or nasvalo, ‘no good’.
