Plural Endings of Everyday Nouns

Most German nouns change their ending in the plural, and the plural article is always die. The main patterns:

• -e: der Tag → die Tage; often with an umlaut: der Stuhl → die Stühle
• -er: das Kind → die Kinder; a, o, u and au always get an umlaut: das Buch → die Bücher, das Haus → die Häuser
• -(e)n: most feminine nouns: die Frau → die Frauen, die Stunde → die Stunden
• -s: many loanwords and nouns ending in -a, -i, -o, -u or -y: das Auto → die Autos, das Handy → die Handys

Always learn a noun together with its plural: das Kind, die Kinder. In this lesson the umlaut is already written in the word, so you only add the ending (Stühl + e = Stühle).
