Mark Liberman has an amusing post at the Log about the emergence of a brand-new peeve:
If you don’t hang out with millennial hipsters, you might not have noticed that the cool kids are listening to music on turntables playing old-fashioned vinyl records, with many of these records being newly released rather than rescued from thrift shops. And you might also have missed a fascinating case of peeve emergence: the “rule” that one of these objects is called a “vinyl”, while (say) three of them should be called “three vinyl”, never “three vinyls”. So instead of “many of these records”, I could have written “many of these vinyl”, but not “many of these vinyls”. This is an issue that some people feel very strongly about.
He quotes many examples of those strong feelings: “Man, I hate to be the school marm but… ‘Vinyls’ is not a word”; “just so you know there is no such word as ‘vinyls.’ The plural of vinyl happens to be vinyl”; etc. etc. He goes into some detail about the silliness of the rule, concluding: “This is an unusually pure case of peevological emergence, without either tradition or logic on its side, and also (as far as i can tell) without any single authoritative figure behind the idea.” People’s need for rules, however arbitrary, both impresses and depresses me.
