(DING-kuhm) Dinkum, also dinky-di, fair dinkum, adjective True; honest; genuine.
Etymology Probably derived, like many other Australian words, from English dialect. The counties of Lincolnshire and Derbyshire had a word or dincum meaning "work; a fair share of work." The word was first recorded in Australia in Rolf Boldrewood's Robbery Under Arms (1888): "It took us an hour's hard dinkum to get near the peak." (© Wordsmith Words)
