Negation in German is how you say 'no' or express that something is not true, does not exist, or is absent. The most common words are 'nicht', 'kein', 'niemand', and 'nichts'.
Use these forms to make sentences negative in German. 'Nicht' is used to negate verbs, adjectives, or entire sentences. 'Kein' is used to negate nouns, especially when talking about things you do not have or that do not exist. 'Niemand' means nobody, and 'nichts' means nothing.
