Masematte is a regional sociolect that used to be spoken in the city's slums and dates back to around 1870. Masematte was initially characterised and spoken by cattle traders, craftsmen and day labourers, including a high proportion of Jews, Sinti and Roma. They were mostly immigrants who were not always welcomed by the local population. The special language developed as a reaction to this rejection.
Masematte is now almost extinct and is rarely used in everyday language - but some words have survived to this day. Münster natives in particular, but also people throughout the Münsterland region, like to use them. Probably the best known of these is "Leeze", the affectionate term of endearment for the bicycle. Other words include "jovel" and "schovel", which translate as "good" and "bad". In summer, the Münster native also likes to go "plümpsen", i.e. swimming. Also important in connection with water: "meimeln". This means "to rain". And before going to the weekly market, city dwellers make sure to put on their "plinte" and pocket their "patte": Pants on - and don't forget your wallet!
And even though the special language is rarely spoken today, it will be declared a UNESCO intangible cultural heritage in 2024! You can find more information about this here.
