influíais

Influíais is a Spanish verb form that corresponds to the second-person plural of the imperfect indicative of influir. In other words, it means “you all were influencing” or “you all used to influence.” It is used with the subject vosotros, which is common in Spain, while in many Latin American varieties the corresponding past is often expressed with ustedes influían.

The form is derived from the verb influir, which means to have an influence or to affect. In the imperfect, influíais follows the regular ending pattern for -ir verbs in the vos­otros form, and carries a written accent on the í to indicate the correct pronunciation and stress: influíais.

Usage notes: influíais denotes past, ongoing, or habitual influence in the past. It can take a direct object (influíais a alguien o algo) or influence en, such as influir en las decisiones, las opiniones, o el curso de un proyecto. In contexts without vosotros, speakers often substitute with ustedes influían or simplemente use another verb to express the idea.

Related forms include influía, influías, influía, influíamos, influíais, influían (imperfect of influir for other person/number combinations) and the preterite influí, influiste, influyò, influimos, influisteis, influyeron. The present tense forms include influís (you all influence) and influye (he/she/you formal influences). Etymologically, influir comes from Latin influere, meaning to flow into, a figurative sense that evolved to mean to have an influence.
