modificáis

Modificáis is the second-person plural present indicative form of the Spanish verb modificar. It is used by speakers who use the vosotros form, primarily in Spain and some parts of the Caribbean and Latin America that maintain this tú/vosotros distinction. The meaning corresponds to “you all modify” or “you all are modifying.”

Etymology and grammar: modificar comes from the Latin modificare, itself built from modi- (measure, manner) and -ficare (to make). In Spanish, modificar is a regular -ar verb, so its present indicative forms follow the standard pattern: yo modifico, tú modificas, él modifica, nosotros modificamos, vosotros modificáis, ellos modifican. The accent on the í in modificáis marks the stress on the syllable where the vosotros form is contracted in speech. The form is used with the implicit subject vosotros, though it can be understood from context without the pronoun.

Usage and regional variation: modificáis is used when addressing a group informally in Spain and regions that retain the vosotros form. In most of Latin America, where vos or ustedes are common, the corresponding present indicative is ustedes modifican (or simply modifican for the third-person plural). For formal or impersonal references, other constructions may be preferred, but modificáis remains a standard, correct form in regions that use vosotros.

Examples: Vosotros modificáis la configuración cada semana para adaptar el sistema a los nuevos requerimientos. Al revisar el informe, modificáis solo los campos necesarios, sin alterar el resto.
