How to use it

  • Use 'cool' in casual spoken German and on social media to mean 'awesome' or 'impressive'. In formal writing or polite settings, choose 'toll', 'großartig' or 'hervorragend' instead.
  • When 'cool' means 'calm and in control', you can say 'bleib cool!' or 'Sie bleibt cool'. With strangers or in formal situations, 'gelassen' and 'ruhig' sound more standard.
  • 'lässig' is for a relaxed, easygoing attitude, outfit or style. It is not the word you use to say that an idea is great.
  • 'geil' is strong slang and originally meant 'arousing'. It is very common among younger speakers for 'awesome', but avoid it with older people and at work.
