Õis

Éis is the second-person plural present indicative ending for regular -er and -ir verbs in Spanish when the subject is vosotros. The ending is written with an acute accent on the e (éís), which marks the stressed syllable. Examples include coméis (you all eat), bebéis (you all drink), escribís (you all write), and vivís (you all live). The ending attaches to the verb stem, as in comer → coméis and vivir → vivís.

Usage and distribution: The vosotros form is standard in Spain and in some other Spanish-speaking regions, but in most of Latin America the second-person plural is expressed with ustedes, with verbs conjugated in the third person plural (ustedes comen, ustedes viven). As a result, the -éis ending is most commonly encountered in Spain and in contexts that preserve the vosotros form.

Phonology and orthography: The accent on é indicates stress on that syllable, consistent with Spanish stress rules for endings that end in s. Other present-tense endings for the vosotros form follow the pattern -áis for -ar verbs (habláis), -éis for -er verbs (coméis), and -ís for -ir verbs (vivís), forming a distinct set of second-person-plural endings across verb classes.
