Someone, anything, no one, everything — these words stand in for a person or thing you're not naming specifically. Learn the pattern behind the whole family, how they team up with the verb, and one rule that trips up a lot of learners: in English, "nobody" and "nothing" are already negative on their own.
What you'll learn
An indefinite pronoun stands in for a person, thing, or amount you're not naming specifically — you don't know who, don't know what, or it just doesn't matter. "Someone called while you were out" doesn't tell you who called; "I need something to drink" doesn't say exactly what.
This lesson focuses on eight of the most common ones: someone, anyone, no one, everyone (for people) and something, anything, nothing, everything (for things).
Notice the pattern: each word is built from a prefix that sets the meaning, plus -one (a person) or -thing (a thing). Some- is used in ordinary positive statements and offers ("Someone is waiting for you," "Would you like something to eat?"). Any- shows up in questions and negative statements ("Did anyone call?" "I don't have anything to add"). No- already means "not one" all by itself ("No one answered," "Nothing happened"). Every- means the whole group, with no exceptions ("Everyone agreed," "Everything is ready").
One spelling note: everyone, everything, someone, something, anyone, and anything are single words — but no one is written as two words. "Noone" isn't standard spelling.
Even though everyone and everything can mean a large group, they act like a single, singular subject in the sentence: "Everyone is here." "Everything looks great." The verb matches the pronoun (singular), not the number of people it might include.
This holds for the whole family: someone/anyone/no one/everyone and something/anything/nothing/everything all pair with a singular verb — is, has, knows, works — not are, have, know, work.
Once you've used someone, anyone, no one, or everyone, you'll often need to refer back to that person again a moment later — and English normally uses "they/their/them" for that, since the pronoun didn't specify gender in the first place: "Someone left their umbrella by the door," "If anyone calls, tell them I'll be back at three."
This is completely standard, everyday usage — not a special exception. The verb right next to someone/anyone/no one/everyone stays singular ("Someone has left..."), while a later "they" refers back to that same person.
No one, nobody, and nothing already carry the negative meaning by themselves. Standard English doesn't add a second negative word to the same idea: "Nobody knows the answer" and "Nothing happened" are already complete, correct negative sentences.
Sentences like "I don't know nothing" or "Nobody doesn't know" double up the negative. Some casual, dialectal speech uses a doubled negative for emphasis, but it is not standard English and isn't accepted in writing, school, or professional contexts. When a verb is already negative (don't, doesn't, didn't, isn't), pair it with an any- word instead of a no- word: "I don't know anything about it," not "I don't know nothing about it."
The verb is already negative ("don't"), so pair it with any-, not no-. Adding a second negative word doubles the negation instead of just meaning "none."
Everyone, everything, someone, and the rest of the family always take a singular verb, even when they refer to a whole group.
For a flat rule that applies to everybody, switch the pronoun to no one instead of putting can't next to anyone — English states the negative once, on the pronoun.
Unlike everyone and someone, no one is spelled as two separate words in standard English.
"Did anyone leave a jacket on the patio?" "I don't think so — everything on the tables is ours." "Good, because no one's come back for anything in the last hour. Let's lock up."
