creáis

Creéis is the second-person plural present indicative form of the Spanish verb creer. It is used with the pronoun vosotros, which is common in Spain and in some regions and contexts. In Latin American Spanish, the equivalent form is ustedes creen.

Morphology and conjugation notes: creer is a regular -er verb in its present indicative, with the standard endings o, es, e, emos, éis, en for each subject pronoun. For vosotros, the ending is -éis, yielding creéis. The form carries an orthographic accent on the e (creéis) to indicate the stress on the second syllable. Full present indicative forms are: yo creo, tú crees, él cree, nosotros creemos, vosotros creéis, ellos creen. A related form, creáis, exists as the vosotros form in the present subjunctive.

Usage and nuance: creéis expresses belief, opinion, or acceptance of something as true in the present. It occurs in questions, assertions, and responses about what the group believes. Examples include: ¿Qué creéis que pasará mañana? (What do you all think will happen tomorrow?) Creéis en la posibilidad de un acuerdo? (Do you believe in the possibility of an agreement?) The use of creéis is tied to the second-person plural vosotos form and contrasts with ustedes creen used in many Spanish-speaking regions outside Spain.

Etymology: creer comes from Latin credere, meaning "to believe" or "to trust." The form creéis reflects the regular present tense paradigm of -er verbs in the vosotras/vosotros form, with the spelling accent serving to indicate stress.
