Incluáis

Incluáis is presented here as a form associated with the Spanish verb incluir, meaning to include. In standard Spanish, however, the present subjunctive for the second-person plural (vosotros) is incluyáis, with a vocalic y after the u. The form without the y—incluáis—is commonly considered a misspelling or nonstandard variant, though it can appear in informal writing or as a typographical error. The correct set of present-subjunctive forms for incluir is: yo incluya, tú incluyas, él/ella/usted incluya, nosotros incluyamos, vosotros incluyáis, ellos incluyan.

Morphologically, incluir is an -uir verb, which triggers a spelling change in the present subjunctive: the stem switches to include the sequence includ- + uy- before the subjunctive endings. This yields includa- for the first person singular and similar forms for the others, with the characteristic y in the vosotros and ellos forms. The present indicative forms are different (yo incluyo, tú incluyes, vosotros incluís, etc.), illustrating how mood and tense affect the verb's spelling.

Usage notes and example: a correct sentence is Es necesario que vosotros incluyáis a todas las personas en la lista. The presence of incluyáis reflects the subjunctive mood used after expressions like es necesario que. If written as incluáis without the y, it would be regarded as nonstandard in formal writing, though readers may still recognize the intended verb.

Etymology and related forms: incluir comes from Latin includere, meaning to enclose or contain. Related forms include incluí, incluye, incluyendo, and the standard subjunctive sequence incluya, incluyas, incluya, incluyamos, incluyáis, incluyan.
