What is sois when translated from Spanish to English?

"Sois" is the second-person plural form of the verb "ser" in Spanish, which means "to be".

So, "sois" translates to "you are" in English, but only when referring to multiple people.

For example:

* "Vosotros sois muy amables." (You are very kind.)

* "Sois los mejores amigos que he tenido." (You are the best friends I have ever had.)

It's important to note that "sois" is not used in all Spanish-speaking countries. It is typically used in Spain and some Latin American countries, while in others, "ustedes son" is used instead.
