asustéis

Asustáis is the second-person plural present indicative form of the Spanish verb asustar. It means “you all scare” or “you all frighten.” This form is standard in Spain, where the informal plural pronoun vosotros is used. In most of Latin America, the corresponding present tense for “you all” is ustedes asustan. Asustáis comes from the regular -ar verb conjugation, using the stem asust- plus the endings -áis for the vosotros form.

Grammatically, asustar is a transitive verb and normally takes a direct object: asustáis a alguien (you all scare someone) or asustáis a la gente con esas historias (you all scare people with those stories). It can also appear in reflexive constructions to express that a group becomes frightened, as in os asustáis (you all get scared). The verb has related forms in other tenses and moods, with asustáis appearing in the present indicative among the vosotros forms, and its subjunctive form being asustéis.

Etymology traces asustar to the noun susto, meaning fright or scare; the verb means to cause such fright. Common synonyms include espantar and atemorizar. In usage, asustáis often appears in informal conversation in Spain, while speakers in other regions may replace it with ustedes asustan in the present indicative.

Examples:

- Vosotros asustáis a los niños con esa historia.

- Os asustáis con facilidad cuando hay tormenta.

- ¿Qué os asusta de esta película?
