büffeln

The German word "büffeln" is an informal verb that means "to cram" or "to study hard," particularly used in the context of preparing for exams. It does not derive directly from compound roots; however, it is colloquially likened to the behavior of a buffalo ("Büffel" in German), humorously implying studying with the intensity or stubbornness of a buffalo.

Similar words in German for intensive studying include "pauken" (to study intensively) and "lernen" (to learn). The main difference between "büffeln" and these words is the informal, somewhat playful connotation of "büffeln," suggesting intense, focused study sessions as opposed to the more generic "lernen," which can apply to any learning activity. "Pauken" also carries a connotation of intense study but is a bit more formal than "büffeln."
