Today’s word scurries between literal and figurative meanings. The German noun Ratte means rat - the animal, yes, but also the sneaky type of person. It’s a word that pops up in biology class, city life, and even gangster films. And, believe it or not, it’s also one of the top 1000 nouns in German!
Ratte is a feminine noun, so the correct article is die - die Ratte. Want a quick and clear way to get German noun gender under control? Watch our 5-minute crash course to learn how to make sense of der / die / das with confidence.
This word is used both literally and metaphorically. A Ratte can be a real rodent - or a human behaving in a sneaky, backstabbing way.
- Da war eine Ratte in der Küche!- Igitt! Ruf den Kammerjäger.(“There was a rat in the kitchen!” - “Gross! Call the exterminator.”)
Or more figuratively:
- Er hat uns verraten.- So eine Ratte!(“He betrayed us.” - “What a rat!”)
Tom: Ich habe eine Ratte im Garten gesehen!Mia: Echt? Lebendig?Tom: Ja, sie ist schnell weggerannt.
(Tom: I saw a rat in the garden!Mia: Really? Alive?Tom: Yeah, it ran off quickly.)
Nominative: Die Ratte läuft durch das Haus.(The rat is running through the house.)
Accusative: Ich habe die Ratte gesehen.(I saw the rat.)
Dative: Ich gebe der Ratte Käse.(I’m giving the rat some cheese.)
Genitive: Der Schwanz der Ratte ist lang.(The rat’s tail is long.)
Need a better grasp of these case changes? Our no-nonsense grammar course explains them in plain English - no jargon, just real understanding.
Nagetier - rodent
Hausratte - black rat (pet rats are called Farbratten)
Wanderratte - brown rat
Laborratte - lab rat
Spitzel / Verräter - snitch or traitor (used more for people)
Figurative expressions:
Du Ratte! - you snake! / you rat!
jemanden als Ratte bezeichnen - to call someone a rat
wie die Ratten das sinkende Schiff verlassen - “rats leaving a sinking ship” (same metaphor in both languages)
The word Ratte appears in many cultural contexts - from street slang to children’s books to idioms:
Rattenfänger von Hameln - The Pied Piper of Hamelin (literally: “rat-catcher”)
Rattenplage - rat infestation
Rattenloch - dumpy, disgusting place (slang)
Note: Ratte is often used with emotional force. It’s rarely neutral when referring to people.
And yes - in biology, the word is sometimes more neutral (Laborratte, weiße Ratte), but in conversation, it often carries a sting.
