Learn Spanish (Latin America): La casa rosada es pequeña.

In Spanish, adjectives (describing words) like colors usually come after the noun they describe. So, instead of 'pink house', you say 'house pink' (casa rosada).

Why do both rosada and pequeña end in the letter 'a'?

Because they are describing la casa, which is a feminine noun. In Spanish, adjectives must match the gender of the noun. The dictionary forms are rosado (pink) and pequeño (small), but we change the ending -o to -a to make them feminine.

Does pequeña still have to match casa even though it comes after the verb es?

Yes! Even when an adjective is separated from its noun by a verb like es (is), it still has to match the noun's gender and number. Since it describes the feminine, singular casa, it must be the feminine, singular pequeña.

Why do we use es here instead of está for 'is'?

We use es (from the verb ser) to talk about permanent or defining characteristics. The size and color of a house are considered fixed physical traits, so we use es rather than está, which is used for temporary states or locations.
