In the other cases the normal subject forms, el, ella, ello, usted, nosotros/as, vosotros/as, ustedes, ellos/ellas, are used after prepositions. Sí and consigoare special prepositional forms of the pronoun se. Seven prepositions or preposition-like words take the ordinary form of all the subject pronouns.
