Questions & Answers about La casa azul es grande.
Why is it azul and not azula to match the feminine word casa?
Adjectives that end in a consonant, like azul, do not change to match masculine or feminine nouns. They only change for plural words (like azules). So, it's el auto azul for a masculine word and la casa azul for a feminine word.
What about grande? Shouldn't it end in '-a' for a feminine house?
Just like adjectives ending in a consonant, adjectives that end in -e do not change for gender. Grande stays exactly the same whether you are talking about a masculine noun (el patio grande) or a feminine noun (la casa grande).
Why does azul come after casa instead of before it?
In English, we say 'the blue house', putting the describing word first. In Spanish, adjectives usually come after the noun they describe. So, you literally say 'the house blue' (la casa azul).
