Learn German: Meine jungen Kühe haben Hunger.

Kühe is a plural noun, and it comes after the possessive article meine. When an adjective describes a plural noun and follows a possessive article (like meine or deine), a definite article (like die), or the negative article keine, the adjective always gets the -en ending.

Why does the sentence use haben Hunger instead of translating 'are hungry' directly?

While you can technically say sind hungrig (are hungry), German speakers usually use the phrase Hunger haben (literally 'to have hunger'). It sounds much more natural in everyday German.

How is the plural word Kühe formed from its singular?

The singular form is die Kuh (the cow). To make it plural, we add an umlaut over the vowel and an -e at the end, making it die Kühe. The plural word meine also gives away that there is more than one cow!

What would happen to the adjective if I just wanted to say 'Young cows are hungry' without the word 'my'?
