German (Deutsch [ˈdɔʏtʃ] ( listen)) is a West Germanic language related to and classified alongside English and Dutch. With an estimated 90 – 98 million native speakers, German is one of the world's major languages and is the most widely-spoken first language in the European Union.

Most German vocabulary is derived from the Germanic branch of the Indo-European language family. Significant minorities of words are derived from Latin and Greek, with a smaller amount from French and English.

German is written using the Latin alphabet. In addition to the 26 standard letters, German has three vowels with umlauts (Ä/ä, Ö/ö, and Ü/ü) and the letter ß.

The history of the language begins with the High German consonant shift during the migration period, separating Old High German dialects from Old Saxon. The earliest testimonies of Old High German are from scattered Elder Futhark inscriptions, especially in Alemannic, from the 6th century AD; the earliest glosses (Abrogans) date to the 8th; and the oldest coherent texts (the Hildebrandslied, the Muspilli and the Merseburg Incantations) to the 9th century. Old Saxon at this time belongs to the North Sea Germanic cultural sphere, and Low Saxon was to fall under German rather than Anglo-Frisian influence during the Holy Roman Empire.
