knibbeln
German
Etymology
Originally, and still chiefly, West Central German. Supposed to belong to knüpfen, regionally knüppen (“to knot”); but given the fact that the dialectal forms invariably have -bb- or -ww- a relation with knabbern (“to nibble”) seems much more likely.
Pronunciation
Verb
- (regional, chiefly western Germany) to scrape with one’s fingernails so as to remove something (e.g. a price tag)
