definisteis

Definisteis is the second-person plural form of the Spanish verb definir in the pretérito indefinido, or simple past. It corresponds to the English phrase you all defined and is used to describe completed actions in the past. The form is characteristic of regions that use the vosotros subject pronoun, especially in Spain.

Morphology and conjugation: Definir is a regular -ir verb, so the preterite forms follow the standard pattern. The full conjugation in the pretérito indefinido is: yo definí, tú definiste, él definió, nosotros definimos, vosotros definisteis, ellos definieron. Definisteis specifically uses the stem defin- with the -isteis ending, producing the spelling definisteis.

Usage notes: Definisteis is primarily found in narrative or dialog within Spain and other areas that use vosotros. In most Latin American dialects, the corresponding past-tense form for ustedes is definieron, not definisteis. As a result, definisteis often marks regional variation and can appear in formal or written works that preserve the vosotros paradigm.

Examples: Ayer definisteis los términos del contrato. Hemos definido las reglas; ahora definisteis cómo aplicarlas. These sentences illustrate how the form indicates a past, completed action addressed to a group.

Etymology and related forms: Definir derives from Latin definire. Related forms in other tenses include defino, defines, define, definimos, definís (present indicative with vosotros), and definieron (third-person plural preterite for ustedes/ellos).
