intercambiasteis

Intercambiasteis is a Spanish verb form that corresponds to the second-person plural in the simple past (preterite) for the verb intercambiar, meaning to exchange or swap. It indicates that you all completed an exchange in the past and is used in narrative or reported past contexts.

Grammatical notes: intercambiasteis is a regular -ar verb conjugation in the preterite for the vosotros form. It is formed from the stem intercambi- plus the ending -asteis, following the standard pattern for -ar verbs in this tense. As such, its use signals a completed action.

Regional usage: The form is standard in Spain, where the pronoun vosotros is common. In many Latin American dialects, ustedes is used instead of vosotros, and the corresponding preterite is intercambiaron (for ustedes) or intercambiaron, depending on the pronoun, rather than intercambiasteis.

Etymology and nuance: The verb intercambiar combines inter- (between, mutual) with cambiar (to change or swap). intercambiasteis emphasizes a mutual or reciprocal exchange among the addressed group.

Examples:

- Ayer, vosotros intercambiasteis regalos en la fiesta.

- En la reunión, intercambiasteis ideas y contactos para futuras colaboraciones.

This form therefore appears in past-tense narration or direct speech involving a group of speakers in dialects that use vosotros, and contrasts with the usted/ustedes forms used in other varieties of Spanish.
