Learn German: Das Hotel ist nicht teuer. - The hotel is not expensive.

kein is used to negate nouns (like saying "not a hotel" or "no hotel"). Since we are negating the adjective teuer (expensive), we must use nicht.

Why is nicht placed right before teuer?

When you are negating an adjective that describes the subject, nicht goes directly in front of that adjective.

If I wanted to ask "How expensive is the hotel?", which W-word do I use?

You would use wie (how). Just like in English, you put the W-word and the adjective together at the start of the sentence: Wie teuer ist das Hotel?

Is there a trick to pronouncing teuer?

Yes! The eu letter combination in German makes an "oy" sound, like in the English word "boy". So, teuer is pronounced roughly like "toy-er".
