introduzcáis

Introduzcáis is the second person plural present subjunctive form of the Spanish verb introducir, used in the vosotros form. It is common in Spain, where the vosotros form is standard; in most of Latin America the corresponding form is introduzcan (ustedes).

Morphology and orthography: The form is built on the stem introduzc-, which comes from the irregular present tense yo introduzco. The endings for the present subjunctive are -a, -as, -a, -amos, -áis, -an, so the vosotros form becomes introduzcáis. This preserves the z-sound before the a in all subjunctive forms of -cir verbs (e.g., introduzca, introduzcas, introduzca, introduzcamos, introduzcáis, introduzcan).

Usage: The present subjunctive is used in subordinate clauses after verbs of volition, doubt, possibility, necessity, emotion, and other expressions that require uncertainty or non-assertion. It typically appears after que, in contexts such as requests, recommendations, or hypothetical statements.

Examples:

- Espero que introduzcáis las pruebas en el sistema antes de la fecha límite.

- Es importante que introduzcáis vuestro nombre completo y datos de contacto.

- Quiero que introduzcáis el código correcto para continuar.

Notes: In Latin American Spanish, the corresponding mood and meaning are conveyed with introduzcan (ustedes) or, in informal speech, ustedes + present subjunctive. The vosotros form is mostly limited to Spain and some influence in education or formal writing. The verb introduces information or items into a system, a form, or a process, aligning with the general sense of "introducir" as to place something inside or to bring forward.
