From Wiktionary:
“Etymology
From Latin quid nunc? (“what now?”).
From Merriem-Webster.com:
“What’s new? That’s a question every busybody wants answered. Latin-speaking Nosey Parkers might have used some version of the expression “quid nunc,” literally “what now,” to ask the same question. Appropriately, the earliest documented English use of “quidnunc” to refer to a gossiper appeared in 1709 in Sir Richard Steele’s famous periodical, The Tatler. Steele is far from the only writer to ply “quidnunc” in his prose, however. You also can find the word among the pages of works by such writers as Washington Irving and Nathaniel Hawthorne.”
