nein

Nein is the standard German word for "no" and for a negative or refusing response. It is an interjection used to deny a question, reject an offer, or express disagreement, often as a brief answer in conversation. For example, "Willst du mitkommen?" "Nein." It can be softened or made more polite with phrases like "Nein, danke" or "Nein, das ist nicht möglich."

In German grammar, nein functions mainly as a direct response; it is not used to negate a noun or a verb in the same way as nicht or kein. For negating predicates, adjectives, or nouns in a sentence, Germans typically use nicht or kein rather than nein.

Pronunciation and spelling: Nein is pronounced with the diphthong ei, similar to the English "nine," and IPA /naɪn/. In informal speech, variants such as "nee" are common; written "nein" remains standard in formal writing.

Etymology and cognates: Nein developed from Old High German neīn or similar forms and shares cognates with Dutch "nee," Norwegian "nei," Swedish "nej," and Danish "nej"—all representing negation or refusal in their languages. The usage of nein as a definitive refusal is widespread across Standard German and remains a fundamental element of everyday communication.
