Learn German: Die Blume ist klein und schön. - The flower is small and beautiful.

You would say Eine Blume ist klein und schön. Because Blume (flower) is a feminine noun, you use the feminine indefinite article eine instead of the masculine or neuter ein.

Why don't the adjectives klein and schön have any special endings?

In German, when adjectives come after the noun and a verb like ist (is), they stay in their basic dictionary form. You only add extra letters to the end of an adjective if it comes directly in front of a noun, like in eine kleine Blume (a small flower).

Is there a rule to help me remember that Blume is a feminine noun?

While you should always try to memorize a noun with its article, a very helpful trick for beginners is that the vast majority of German nouns ending in -e (like Blume) are feminine. This means they will use die for 'the' and eine for 'a'.

What if I can't type the two dots over the ö in schön?

If you don't have a German keyboard, you can replace the umlaut (the two dots) by adding an e after the vowel. So, you can type schoen and it is completely correct!
