restaréis

Restaréis is a verb form in the Spanish language. It specifically represents the second-person plural future indicative conjugation of the verb "restar". The verb "restar" primarily means "to subtract" or "to remain". Therefore, "restaréis" translates to "you all will subtract" or "you all will remain".

In its most common usage, when referring to subtraction, "restaréis" would be used in a sentence like "Vosotros restaréis diez de veinte" which means "You all will subtract ten from twenty". In this context, it describes a future action of performing a mathematical subtraction.

The alternative meaning of "remain" or "be left" is also possible. For instance, "Si comemos todo esto, no nos restaréis nada" could be translated as "If we eat all of this, nothing will remain for you all" or "nothing will be left for you all". This usage is less frequent than the subtraction meaning but still valid.

The form "restaréis" is characteristic of the vosotros conjugation, which is primarily used in Spain. In most Latin American countries, the ustedes form ("restarán") is used for both formal and informal second-person plural address. Therefore, encountering "restaréis" strongly suggests the text originates from or is intended for a Spanish audience.
