Which is correct: each of you is or each of you are?

The correct grammar for the phrase in question is "each of you is."

The word "each" is traditionally considered a singular pronoun, and it should be paired with a singular verb. Here are some sources that support this:

• "Each of you is" is the correct grammar because "each" is a singular pronoun34.
• The traditional rule holds that the subject of a sentence beginning with "each" is grammatically singular, and the verb and following pronouns must be singular24.
