Questions & Answers about La casa es amarilla.

Why is it amarilla instead of amarillo?
Adjectives in Spanish change their endings to match the noun they describe. Because casa (house) is a feminine noun, the base word for yellow, amarillo, changes its ending to match and becomes amarilla.
If I want to say 'the yellow house', does the word order change?
Yes! This sentence uses es (is), so the order matches English. But if you want to say 'the yellow house' as a single phrase without the word 'is', the adjective goes right after the noun in Spanish: la casa amarilla.
Why do we use es instead of está for 'is'?
We use es (a form of the verb ser) to talk about permanent descriptions and inherent qualities. A house's physical color is considered a basic characteristic, so we use es rather than está.
How do we know casa is a feminine noun?
Most Spanish nouns that end in the letter -a, like casa, are feminine. That is why it uses the feminine word for 'the' (La) and forces the adjective to also end in -a (amarilla).
