Learn Italian: Quel cielo rosso è strano.

When 'that' is placed right before a noun, it changes its ending based on the noun's gender and starting letters. It follows the exact same pattern as the definite article (the word for 'the'). Because you would say il cielo, the demonstrative adjective drops its ending to match, becoming quel cielo. You would only use the full quello if the noun used the article lo (for example, quello specchio).

Why does rosso come after cielo instead of before it?

In Italian, descriptive adjectives—especially colors, shapes, and nationalities—usually come right after the noun they describe. So, instead of 'red sky', you say cielo rosso (sky red).

Do rosso and strano both end in -o to match cielo?

Yes! Cielo is a masculine singular noun. In Italian, any adjective describing a noun must agree with its gender and number. This is why you use the masculine singular -o ending for both rosso and strano.

Why is there an accent mark on è?

The accent mark is crucial because it completely changes the word's meaning. With the accent, è means 'is' (from the verb essere, to be). Without the accent, e just means 'and'.
