Learn Spanish (Latin America): Su embarazo es una buena noticia.

No, this is one of the most famous "false friends" in Spanish! Embarazo means "pregnancy." If you want to talk about "embarrassment," you would use the word vergüenza. To say someone is embarrassed, you would say they are avergonzado or avergonzada.

Why does the sentence say una buena noticia if we just say "good news" in English?

In English, "news" is an uncountable noun, so we never say "a good news." In Spanish, however, the word noticia is countable. You use the singular una noticia to talk about a single piece or item of news, and the plural noticias to talk about the news in general.

Since this lesson is about ser and estar, what does the adjective bueno mean with each verb?

Here we use ser (es) because we are identifying what the pregnancy is (a piece of good news). When used as a standalone adjective, ser bueno means something or someone is fundamentally good, high-quality, or kind. If you use estar bueno, the meaning changes completely! It usually means that food is very tasty, or in casual speech, that a person is physically attractive.

Why is buena placed before noticia instead of after it?
