❓ Frequently Asked Questions (FAQ)

Q1: What is the difference between "someone" and "somebody"?

There is no difference in meaning! "Someone" is slightly more common in formal writing, while "somebody" is very common in informal speech.

Q2: Why do we use "they/them" to refer back to "everyone"?

Even though "everyone" takes a singular verb ("Everyone is here"), English speakers use gender-neutral plural pronouns ("they/them") to refer back to it: "Everyone is bringing their own lunch."

Yes! When it means "it doesn't matter who": "Anybody can join this club" (ai cũng có thể tham gia).
