Questions & Answers about Beide Kinder sind müde.
Here, beide is right in front of Kinder. Can it replace the noun completely like einer or keiner?
Absolutely! Just like the indefinite pronouns in this lesson, beide can stand alone. If we already know we are talking about the children, we can drop the noun and simply say Beide sind müde (Both are tired).
Why does beide end in -e in this sentence?
Beide is acting like an adjective attached to a plural noun (Kinder). Since it is the subject (nominative case) and there is no word for 'the' in front of it, it takes the standard plural ending -e.
Why doesn't müde have a plural ending to match the children?
In German, adjectives only change their endings when they come directly before a noun, like in die müden Kinder (the tired children). When an adjective comes after a verb like sind, it stays in its basic dictionary form.
