Learn Portuguese (Portugal): A nossa casa é velha, tem sessenta e cinco anos. - Our house is old, it is sixty-five years old.

In Portuguese, you combine the tens and the units using e (and). So, 65 is literally sixty and five: sessenta (sixty) plus e (and) plus cinco (five). This pattern is used for all numbers from 31 to 99.

Why does it say tem (has) instead of using a verb for "is" to talk about the house's age?

In English, we say someone or something "is" a certain age. In Portuguese, we use the verb ter (to have) for age. You are literally saying that the house "has" sixty-five years.

Why is there an A before nossa casa?

In European Portuguese, it is standard to put a definite article (like o or a, meaning "the") before a possessive word. Since casa is a feminine noun, we use A nossa instead of just nossa.

Why is the word for old spelled velha instead of velho?

Adjectives must match the gender of the noun they describe. Because casa (house) is a feminine word, the adjective for old changes from its default masculine form velho to the feminine form velha.
