gup n.1

also gup-gup, gup-shup
[Hind. गप (gap), gossip, rumour, which borrowed in turn from the Turkish gep or geb, word, saying or talk and the Persian guftan or guptan, to say. The word made its way to the UK c.1868, the year in which a highly critical account of South Indian society was published under the pseudonym of ‘Gup’; thus Hind. गाप-शाप (gap-śāp), reduplicative of गप (gap), gossip, rumour]
