This is a grammatically valid English sentence:

Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.

It was discovered/invented in 1972 by University of Buffalo linguist William J. Rapaport. It means “Buffalo from the city of Buffalo that are intimidated by other buffalo from the city of Buffalo themselves intimidate a third group of buffalo, also from Buffalo.”

Is that clear? Be glad you’re not in the Netherlands, where Als In Bergen, bergen bergen bergen bergen bergen bergen bergen bergen bergen bergen means “If in Bergen, heaps of mountains salvage heaps of mountains, then heaps of mountains salvage heaps of mountains.”
