Mine, yours, his, hers, ours, theirs — six small words that can stand in for a whole phrase. Say "This is mine" instead of "This is my book," and skip the apostrophe every single time.
What you'll learn
A possessive pronoun stands completely on its own — it takes the place of a whole phrase like "my book" or "her car," not just part of one. Instead of repeating the noun, you swap the entire "my/your/etc. + noun" phrase for a single word: "This is my book" becomes "This is mine."
English also has words like my, your, and her that go directly before a noun (my book, her car) — you'll meet those in more detail elsewhere. This lesson is only about the six words that replace the noun completely and stand by themselves.
There is one standalone possessive pronoun for each person: mine (belongs to me), yours (belongs to you), his (belongs to a male person), hers (belongs to a female person), ours (belongs to us), and theirs (belongs to them).
Notice that his looks exactly the same whether it comes before a noun (his car) or stands alone (This car is his) — it's the one word on this list that doesn't change form. The other five — mine, yours, hers, ours, theirs — are used only in the standalone position, never directly in front of a noun.
None of these six words ever takes an apostrophe. There's no such spelling as her's, your's, their's, or our's — those forms simply don't exist in English.
That can feel surprising, because English does use an apostrophe for possession elsewhere, like in Tom's car or the dog's bed. Possessive pronouns are the exception: mine, yours, his, hers, ours, and theirs are already complete possessive words on their own, so they don't need — and never get — an apostrophe.
You might expect a standalone form for it too, but English doesn't really have a natural one. "This is its." sounds incomplete — it isn't something a native speaker would actually say.
When you need to talk about something belonging to an object or an animal, English usually keeps its directly in front of the noun instead ("This is its cover") or simply repeats the noun ("This is the box's lid"). English just doesn't split "it" into a separate standalone possessive word the way it does for people.
Hers never takes an apostrophe. There's no such word as her's — hers is already the complete possessive form.
Same rule for theirs: no apostrophe, ever. It's one solid word, just like hers, yours, and ours.
Mine can't go directly in front of a noun — that job belongs to my. Mine only appears on its own, standing in for the whole phrase ("I need mine" = "I need my keys").
"Its" almost never stands alone the way mine or hers can. Keep it in front of a noun, or repeat the noun, instead of leaving it by itself.
"Whose stapler is this — yours or mine?"
"I think it's mine. Yours has a sticker on the side, remember?"
"Good point. Then these highlighters are ours, and that box by the printer is theirs."
"Perfect — everything's sorted."
