Note 44.2 — LOS INTERESES CREADOS
Reading edition
llamasteis. As the modern form would be either llamaste or llamó (according to whether the speaker uses tú or usted), llamasteis is an archaism and properly corresponds to the archaic form of address vos. Here living Spanish requires (usted) llamó, or (tú) llamaste, if the speaker may appropriately use tú. Vos is confined to poetic style, and to solemn addresses, for instance, to God, to royalty, or to high dignitaries, etc.
Everywhere in Los intereses creados we find vos instead of usted and, consequently, vuestro etc. instead of su or de usted. With vos the verb must of course be in the true second person plural (e.g. llamáis). See the note on la antigua farsa, [39.2]. See Bello-Cuervo, §§ 234, 235.
