chequeasteis
Chequeasteis is the second-person plural preterite form of the Spanish verb chequear, meaning "you all checked." It is used with the vosotros form, which is typical of Spain and some other regions that maintain the informal plural second person. The preterite indicates a completed action in the past, often within a narrative or a specific past moment.
Chequear is a regular -ar verb, so its standard preterite forms are: yo chequeé, tú chequeaste, él/ella/usted
Regional variation is notable. In most Latin American varieties, the vosotros forms are not used; speakers instead
Chequear derives from the noun cheque (check) and has the general sense of examining, verifying, or confirming
