olvidasteis

Olvidasteis is the second-person plural form of the Spanish verb olvidar in the pretérito indefinido (also called pretérito perfecto simple). It corresponds to “you all forgot” in English and is used with the vosotros form, primarily in Spain. In many Spanish-speaking regions outside Spain, vosotros is not used, and olvidar is conjugated as olvidaron for ustedes or ellos.

Conjugation and form: olvidar is a regular -ar verb. Its key forms in the preterite include: yo olvidé, tú olvidaste, él/ella/Ud. olvidó, nosotros olvidamos, vosotros olvidasteis, ellos/ellas/Uds. olvidaron. The form olvidasteis shows the -asteis ending typical of the vosotros preterite and does not carry an accent mark on olvidasteis.

Usage notes: The vosotros forms, including olvidasteis, are standard in Spain and in some regional varieties but are uncommon or absent in most of Latin America, where ustedes or ellos are used with corresponding preterite forms (olvidaron). The preterite tense expresses a completed action at a definite point in the past, rather than a continuing or habitual action. Olvidasteis can be used with time indicators like ayer, la semana pasada, o en aquel momento.

Examples:

- Ayer olvidasteis las llaves. (Yesterday you all forgot the keys.)

- ¿Olvidasteis traer el libro? (Did you all forget to bring the book?)

Resumo: olvidasteis is a regular, vosotros-specific preterite form signaling a completed past action, most common in Spain and in contexts where the vosotros form is used.
