ustedes

Spanish personal pronouns have distinct forms according to whether they stand for the subject (nominative) or object, and third-person pronouns make an additional distinction for direct object (accusative) or indirect object (dative), and for reflexivity as well. Several pronouns also have special forms used after prepositions. Spanish is a pro-drop language with respect to subject pronouns, and, like many European languages, Spanish makes a T-V distinction in second person pronouns that has no equivalent in modern English. Object pronouns can be both clitic and non-clitic, with non-clitic forms carrying greater emphasis. With clitic pronouns, proclitic forms are much more common, but enclitic forms are mandatory in certain situations. There is significant regional variation in the use of personal pronouns, especially second-person pronouns.
