Obedecisteis

Obedecisteis is the second-person plural form of the verb obedecer in the pretérito indefinido (preterite) used with the pronoun vosotros. It means “you all obeyed” and is common in Spain, where the vosotros form is standard. In many Latin American dialects, the vosotros form is not used, and ustedes obedecieron is the typical equivalent.

Conjugation and form: Obedecisteis is formed from the stem obedec- plus the ending -isteis. For obedecer, the full preterite is: yo obedecí, tú obedeciste, él obedeció, nosotros obedecimos, vosotros obedecisteis, ellos obedecieron. The 3rd-person plural ends with -eron (obedecieron), which is characteristic of many -ecer verbs in the preterite.

Usage notes: The form is primarily literary or regional to Spain and may be found in formal writing or narration that uses the vosotros form. In Latin American Spanish, one would normally use ustedes obedecieron or, less commonly, ustedes obedecieron as the past tense equivalent. The verb denotes completed past action of obedience, and the corresponding imperfect form would be obedecía(s) in the appropriate person.

Examples:

- Vosotros obedecisteis las órdenes sin cuestionarlas. (You all obeyed the orders without questioning them.)

- En la historia, ustedes obedecieron al jefe y siguieron las instrucciones. (In the story, you all obeyed the boss and followed the instructions.)

In practice, the exact pronunciation varies by dialect, with Castilian Spanish and Latin American varieties differing in certain consonant sounds around ce/ci sequences.
