avergonzado vs embarazada
The most embarrassing false friend. 'Estoy embarazada' is not 'I'm embarrassed' — it means 'I'm pregnant'.
avergonzar / dar vergüenza
To embarrass or shame. Estar avergonzado or tener/dar vergüenza.
Me da vergüenza hablar en público.
I'm embarrassed to speak in public.
Dar vergüenza follows the gustar pattern. The most natural way to say it.
Estoy avergonzado por lo que dije.
I'm ashamed of what I said.
Avergonzado = ashamed, a real regret.
¡Qué vergüenza!
How embarrassing!
Exclamation, widely used. In Spain you'll also hear 'qué corte'.
embarazar / estar embarazada
Embarazada means pregnant. It never means embarrassed.
Mi hermana está embarazada de seis meses.
My sister is six months pregnant.
The only meaning of the adjective. Used only for women.
Se quedó embarazada en mayo.
She got pregnant in May.
Quedarse embarazada = to get pregnant.
Me puse rojo de vergüenza.
I went red with embarrassment.
What to say instead when you mean embarrassed. Ponerse rojo works well.
Tricky bit
Say 'estoy embarazada' to a Spanish speaker thinking 'I'm embarrassed' and you've announced a pregnancy. Use 'me da vergüenza' or 'estoy avergonzado/a'.
