“Yeah, nah” made it into the Oxford English Dictionary in June 2026. Two words, one very Australian way to answer.

Used in Australia and New Zealand, “yeah, nah” depends heavily on context. It can acknowledge what someone has said before disagreeing—something like, “I hear you, but no.” “Want to get up at 5 am for a run?” “Yeah, nah.” Oxford included the phrase in its June 2026 update. Australians and Kiwis didn’t need a dictionary to understand it, but everyone else now has somewhere to look.
