Invalidasteis

Invalidasteis is the second-person plural preterite form of the Spanish verb invalidar. It translates to “you all invalidated” or “you all voided,” and is used to describe a completed action in the past involving rendering something invalid, void, or inapplicable.

Etymology and meaning: The verb invalidar comes from Latin invalidare, from in- “not” and validus “strong,” historically meaning to render invalid, null, or unenforceable. In modern Spanish, invalidar can have several nuanced senses, including declaring something legally or technically void, doubting or discrediting a claim, or undermining a method or result.

Usage notes: The form invalidasteis belongs to the vosotros conjugation, which is characteristic of Spain and some regional varieties. In most Latin American dialects, the vosotros forms are replaced by ustedes, whose preterite forms are invalidaron. Therefore, in Latin America you would more commonly encounter “ustedes invalidaron” rather than “vosotros invalidasteis.”

Grammatical properties: invalidasteis is a preterite (simple past) tense form, not imperfect, used for actions completed in the past. It uses the stem invalid- with the typical -asteis ending for -ar verbs in the vosotros form.

Examples:

- Ayer invalidasteis la solicitud por falta de documentos.

- El comité afirmó que invalidasteis el procedimiento anterior.

Related terms: invalidar (infinitive), invalidado (participial/adjective form), invalidación (noun). In legal or administrative contexts, the term often appears alongside commands to declare something invalid or to nullify a decision.
