How do people use Einen Kater haben?

Everyday German, a touch informal but fine almost anywhere. In the past: “ich hatte einen Kater”. People love to size it up: “einen schrecklichen Kater”, “einen mächtigen Kater”, or the compound “Mordskater” (a killer hangover). Because Kater also means a male cat, “hast du einen Kater?” can be a question about pets, and context does the rest.

Where does Einen Kater haben come from?

There are two explanations and no certainty. Kluge’s etymological dictionary, cited by German Wiktionary, says the word turned up in the 19th century among Leipzig students, where Kater was a name for a kind of beer. English Wiktionary instead calls it a joking twist on Katarrh (catarrh), helped along by the older word Katzenjammer, a cats’ wailing. Either way, the cat is most likely a pun and not the point.

Mistakes learners make with Einen Kater haben
