confirmasteis

Confirmasteis is the second-person plural preterite (pretérito perfecto simple) indicative form of the verb confirmar in Spanish, used with the pronoun vosotros. It means "you all confirmed" in English. The form is regular for -ar verbs in this tense: the ending for vosotros is -asteis, so confirmar becomes confirmasteis.

Use of vosotros forms, including confirmasteis, is standard in Spain and in some regional varieties. In most of Latin America, aims of formality and familiarity are expressed with ustedes, and the corresponding preterite form is ustedes confirmaron. Therefore, confirmasteis is common in Spain and in contexts where the vosotros form is accepted, but it is less frequent in many Latin American dialects.

Pronunciation varies by dialect, but the syllable structure is typically pronounced with the stress on the "mas" syllable and a final "teis" sound, roughly con-fi- rmas-teis.

Examples:

- Ayer confirmasteis la reserva para la cena. (Yesterday you all confirmed the reservation for the dinner.)

- ¿Confirmasteis vosotros la hora de la reunión? (Did you all confirm the time of the meeting?)

Related forms include confirmo, confirmas, confirma, confirmamos (present and other tenses with different subjects), and confirms with other persons and tenses. In regions where vosotros is not used, the corresponding preterite for ustedes is confirmaron.
