Where I live, in the Ruhr-area, two origin Polish words are used. They are quite common since 100 to 120 years, when there was a big immigration of Polish coalmine-workers. Also a reason, why here are still a lot of family-names are ending with ..ski and ..iak.

One is "Mottek" for a hammer and the other "Matka" for a girl. But "Matka" is more in a negative meaning, for a stupid, clumsy oaf of a girl.
