Have you ever heard of the inchoative increment? If it doesn't ring a bell, neither do false inchoative verbs... But if you have ever heard in Central Catalan a construction similar to 'No 'I know this boy' and the verbal conjugation has sounded strange to you, it’s a very good sign: implicitly you know that something is creaking (because the conjugation admitted by the regulations is precisely the one shared by all dialects: ‘conec’).
