Use of the subject pronoun
Although the Spanish language has a high number of personal pronouns, the subject pronouns are usually omitted from the sentence – since the endings of the verb already show clearly enough who the subject of the sentence is.
But for a certain purpose the personal pronouns are still needed, e.g:
– to stress someone
¿Has comido tú el pan? – Did you eat the bread?
No, él ha roto el vaso – No, he broke the glass.
– to identify someone exactly
¿Quién es? – Soy yo – Who’s that? It’s me
¿Es usted la Señora Martín? – Are you Mrs. Martín?
– to distinguish between different persons
Chicas, ¿vostras vaís a salir esta noche? – Girls, are you going out tonight?
Por supuesto, nosotras vamos a salir al cine – Of course, we’ll go to the movies.
For us, for you and for her we use the feminine form when we talk exclusively about women: nosotras, vosotras, ellas.
However, if at least one male person is present, nosotros, vosotros or ellos is used.
