Spanish pronouns
Spanish pronouns in some ways work quite differently from their English counterparts. Subject pronouns are often omitted, and object pronouns come in clitic and non-clitic forms. When used as clitics, object pronouns can appear as proclitics that come before the verb or as enclitics attached to the end of the verb in different linguistic environments. There is also regional variation in the use of pronouns, particularly the use of the informal second-person singular vos and the informal second-person plural vosotros. Personal pronouns Personal pronouns in Spanish have distinct forms according to whether they stand for a subject (nominative), a direct object (accusative), an indirect object (dative), or a reflexive object. Several pronouns further have special forms used after prepositions. Spanish is a pro-drop language with respect to subject pronouns. Like French and other languages with the T–V distinction, Spanish has a distinction in its second person pronouns that has no equivalent in modern English. Object pronouns come in two forms: clitic and non-clitic, or stressed. With clitics, object pronouns are generally proclitic, but enclitic forms are mandatory in certain environments. The personal pronoun "vos" is used in some areas of Latin America, particularly in Central America, Argentina, Uruguay, Paraguay, Chile,
