llaméis

Llaméis is the second-person plural form of the present subjunctive of the Spanish verb llamar, which means "to call" or "to name." In the present subjunctive, the forms of llamar are: llame (yo), llames (tú), llame (él/ella/Ud), llamemos (nosotros), llaméis (vosotros), llamen (ellos/Uds). Llamar is a regular -ar verb, so its subjunctive endings follow the standard pattern.

This form is used in subordinate clauses that express doubt, desire, emotion, necessity, or possibility, and in clauses introduced by conjunctions such as para que, sin que, a menos que, among others. It is the appropriate form when the subject is vosotros in contexts requiring the present subjunctive. For example: Es importante que vosotros llaméis antes de venir. Espero que llaméis cuando lleguéis. Ojalá que llaméis mañana.

Regional usage varies. In most Spanish varieties that do not use the vosotros form, the corresponding subjunctive for the second person plural is llamen (ustedes), as in Es importante que llamen antes de venir. Therefore, llaméis is primarily used in Spain and other regions where the vosotros form is standard; in Latin American Spanish, the ustedes form is typically used instead.

In summary, llaméis is the present-subjunctive vosotros form of llamar, employed in contexts requiring the subjunctive for addressing multiple informal listeners.
