reemplasteis

Reemplasteis is the second-person plural preterite form of the Spanish verb reemplazar, used to indicate that you all replaced something in the past. This form is part of the regular conjugation pattern for -ar verbs in the pretérito indefinido in the vosotras/vosotros (you all) form.

In standard Spanish, the second-person plural preterite for this verb is reemplazasteis, spelled with the sequence -azasteis. The form "reemplasteis" (without the -za-) is considered incorrect in most dialects that distinguish vosotros; the correct vosotros form retains the -z- before -asteis because the infinitive is reemplazar. The full paradigm for reemplazar in pretérito indefinido is: yo reemplacé, tú reemplazaste, él reemplazó, nosotros reemplazamos, vosotros reemplazasteis, ellos reemplazaron.

Usage varies by region: replacing with vosotos is common in Spain, where the vosotros forms are standard. In most of Latin America, ustedes is used instead of vosotros, and the corresponding past tense is reemplazaron (the third-person plural form). The meaning remains the same across dialects: to substitute one thing for another in the past.

Examples:

- Ayer reemplazasteis el componente defectuoso por uno nuevo. (Spain)

- En América Latina, ustedes reemplazaron las piezas y el equipo funcionó mejor.
