A list of some of the most common German homonyms that are spelled the same but mean something different. They are useful to know and with some it could get weird if you mix them up. Some of them also have a different plural form

der Strauß
the ostrich (pl.: die Strauße)
the bouquet (pl.: die Sträuße)
