Basic ways to say “cool” in German

In modern spoken German, the English word cool is widely accepted and feels completely natural. You will hear it in casual conversations with friends, in relaxed workplace chats and in everyday digital communication. It is often the simplest and most reliable choice when you want to react positively to an idea, an event or a piece of news.

In formal or professional writing, however, cool can sound too relaxed. German Emails to clients, academic texts or official documents usually require a more neutral tone. Expressions such as super, toll, gut or interessant fit these situations more comfortably because they sound polite and straightforward.

If you are learning German you might feel overwhelmed by the long lists of alternatives they find online, but only a few words truly matter for everyday German. Most speakers rely on cool for casual situations and choose super or toll when they want to keep things neutral. The slang options come into play only when the conversation is clearly informal.

Examples for “cool” in German

Das ist echt cool.
That’s really cool.

Der Plan klingt cool — lass uns das machen.
The plan sounds cool — let’s do it.

Sie hat einen coolen Stil.
She has a cool style.

Die Ausstellung war cool, aber ein bisschen chaotisch.
The exhibition was cool but a little chaotic.

Common mistakes with “cool” vs. “geil”

One of the most frequent mistakes is using geil to describe a person in German in  a neutral social or professional context. While geil is common slang for something exciting or impressive, it can sound sexual when applied to people. Another mistake is using cool in a very formal email, where a more neutral phrase would sound more appropriate. Learners also sometimes translate every English “cool” word-for-word, even when German speakers would prefer a clearer, more specific adjective.

Here are a few micro-examples that show how meaning shifts:

Die Idee ist geil.
This sounds enthusiastic and informal.

Der Typ ist geil.
This easily carries a sexual meaning and should be avoided unless it is intentional.

Vielen Dank für Ihre Unterstützung. Das ist cool.
This feels too casual for a formal message.

Slang options: “geil”, “krass”, “hammer” and more

Slang expressions allow you to sound lively and expressive in informal German. They are common in youth culture, friend groups and relaxed online chats, but they are rarely used in professional or formal settings. The most reliable options are geil, krass and hammer. Below you’ll find their meanings and how German speakers typically use them.

geil

• Meaning: awesome, fantastic
• Tone: very informal
• Use it for: exciting events, achievements or impressive experiences
• Avoid for: describing people in neutral or professional contexts

Das Konzert war einfach geil.
The concert was absolutely awesome.

krass

• Meaning: intense, surprising or impressive
• Tone: informal and modern
• Use it for: strong or surprising reactions

hammer

• Tone: informal
• Use it for: very enthusiastic reactions

The movie was amazing.

Other informal mentions
