After a binge of Ed McBain books a few months ago – they often touch on linguistic topics – this week I picked another of his 87th Precinct series off the unread shelf: Let’s Hear It for the Deaf Man (1973). It uses a form of the Yiddish word kibitz twice in short succession:
In the April sunshine four fat men sit at a chess table in the park across the street from the university. All four of the men are wearing dark cardigan sweaters. Two of the men are playing chess, and two of them are kibitzing, but the game has been going on for so many Sundays now that it seems almost as though they are playing four-handed, the players and the kibitzers indistinguishable one from the other.
Kibitz is a handy word that means to watch someone do something (normally a game, often cards) and offer unwelcome advice. It can also simply mean to chat or joke around. The word entered English almost a century ago via multiple languages, thieves’ cant, and ornithological onomatopoeia. This delightful etymology is summarised at Etymonline:
