Learn Finnish: Auto on sininen.

Finnish doesn't use articles like "a", "an", or "the". The word auto can mean "car", "a car", or "the car". You have to figure out which one it is from the context of the conversation!

How would I say "the blue car" instead of "the car is blue"?

Just like in English, you put the adjective right before the noun. "The blue car" would be sininen auto. In our sentence, sininen comes after the verb on (is) to describe the subject.

The word sininen ends in -nen. Is this a common ending for adjectives?

Yes, very common! Many adjectives, including other colors like punainen (red) and valkoinen (white), end in -nen. Keep an eye on these -nen words, as their endings change in a special way when you use them in different grammatical cases later on.

What if there were multiple cars? How would this exact sentence change?

Everything in the sentence would need to turn plural. Auto becomes autot (cars), the verb on becomes ovat (are), and the adjective sininen becomes siniset (blue). So, "The cars are blue" is Autot ovat siniset.
