Questions & Answers about ¿Quién es esa mujer?
Why do we use quién here instead of quiénes?
Quién means "who" when we are asking about one person. Because we are asking about one single woman (esa mujer), we use the singular form. If we were asking about multiple women, we would use the plural form quiénes.
Why does quién have an accent mark over the 'e'?
In Spanish, all question words (like quién, qué, and dónde) have an accent mark to show they are asking a question. This helps tell them apart from the same words used in normal statements.
Why do we use es instead of está to mean "is"?
Why is the word for "that" esa and not ese or eso?
