I study in Slovenia for student exchange. I sit on a pair on the history of the Slovenian language, the theme is consonantism (development of consonants), and the predecessor as an example of the development of diftong "sc" gives the verb "scat". Silence in the audience, an uncertain voice: “That’s not... emm... a book word?”
Preponja: Yes, this is a word from the spoken language, but, first, it gives a good example of the diptong, and secondly, we use this word in everyday speech, and so let us not lie to our colleague from another country that we do not have such a word.
