Saying you’re “embarazada” to say you’re embarrassed in Spanish is a case of English to Spanish direct translation gone wrong. Some words that sound the same in both languages often have different meanings and can lead to embarrassing situations.
A cognate is a word that looks similar in English and Spanish and has the same meaning in both languages. Embarazada is a false cognate, a word that looks the same in both languages and sounds similar but has a different meaning.
Embarazada means pregnant! Nothing close to being embarrassed.
