Possessive Pronouns: Choose the Right Form

Can I use 'its' as a standalone possessive pronoun?

Possessive adjectives and possessive pronouns both signal ownership or close connection. Possessive adjectives introduce a noun phrase, telling your listener who holds or claims that noun. Possessive pronouns take the place of that entire possessive noun phrase, allowing you to refer to the owned item without saying its name twice.

ポイント

  • Check whether a noun follows your possessive word.
  • If the possessive introduces a noun phrase, choose my, your, his, her, its, our, or their.
  • If the noun has already been established and stands earlier in the sentence, use mine, yours, his, hers, ours, or theirs.

Decide Whether a Noun Follows the Word

Before you select a possessive word, look at the position right after the blank. If the possessive introduces a noun, possibly with descriptive words in between, you need a possessive adjective such as my, your, or their. When no noun follows because the thing is already known, select a standalone possessive pronoun such as mine, yours, or theirs.

  • Your jacket is on the chair.

    この表現を使う理由: The noun jacket comes directly after your.

  • The jacket on the chair is yours.

    この表現を使う理由: Yours replaces your jacket and stands alone at the end.

自分で試す

Which word correctly completes: 'Please hand me ___ umbrella'?

答えを見る

答え: your

Because the noun umbrella follows immediately, you must use the possessive adjective your.

Place Possessive Adjectives Directly Before Nouns

A possessive adjective introduces a noun phrase, and descriptive words can come between it and the noun. His can also stand alone as a possessive pronoun. Her can stand alone as an object pronoun, but the standalone possessive form is hers. Choose the form according to its job in the sentence, rather than assuming these words always need an immediately following noun.

  • Our team finished the project ahead of schedule.

    この表現を使う理由: Our specifies who owns or comprises the team.

  • Their office moved to the fifth floor.

    この表現を使う理由: Their introduces the noun office.

Which sentence uses a possessive adjective correctly?

答えを見る

答え: Their notebook is on the table.

Their must sit directly before the noun notebook to show possession correctly.

Replace Repeated Nouns with Possessive Pronouns

When you already named an object earlier in the conversation, repeating that noun makes your speech sound heavy and robotic. Possessive pronouns like mine, yours, hers, ours, and theirs bundle the owner and the noun together, creating clean and natural sentences without clumsy repetition.

  • My coffee is hot, but yours is already cold.

    この表現を使う理由: Yours replaces your coffee so you do not have to repeat the noun.

  • We brought our tickets, and they brought theirs.

    この表現を使う理由: Theirs stands for their tickets at the end of the second clause.

自分で試す

Which option best avoids repeating the noun in: 'Her car is parked outside, and my car is in the garage'?

答えを見る

答え: ...and mine is in the garage.

Mine replaces my car entirely, so no noun should follow it.

Recognize Words That Share One Form

Most possessive adjectives add an s or change spelling when they become pronouns, such as your turning into yours and my turning into mine. However, the masculine word his keeps the exact same spelling in both roles. You must look at the sentence structure around it to know whether it modifies a noun or stands alone.

  • His phone rang during the meeting.

    この表現を使う理由: His acts as an adjective before phone.

  • That coat on the rack is his.

    この表現を使う理由: His acts as a possessive pronoun standing alone.

自分で試す

In the sentence 'The blue backpack is his,' what role does 'his' play?

答えを見る

答え: A possessive pronoun replacing his backpack

Because his stands alone after the verb is without a following noun, it functions as a possessive pronoun.

Distinguish Its from It Is in Writing

One of the most frequent writing errors involves mixing up its and it is. The word its without an apostrophe shows possession for a thing, organization, or animal. The form with an apostrophe is always a contraction for it is or it has, never a possessive word.

  • The printer lost its network connection.

    この表現を使う理由: Its shows that the network connection belongs to the printer.

  • It's time to replace the printer paper.

    この表現を使う理由: It's is the contraction for it is.

自分で試す

Which sentence correctly shows ownership?

答えを見る

答え: The cat licked its paw.

The possessive adjective its does not use an apostrophe when showing ownership.

Leave Apostrophes Off All Possessive Pronouns

Learners often see the final s on yours, hers, ours, and theirs and assume an apostrophe belongs before or after that s. English never uses apostrophes in possessive pronouns. These words are already fully possessive by nature, so adding punctuation creates an incorrect spelling.

  • That presentation slide was ours.

    この表現を使う理由: Ours is spelled without an apostrophe.

  • The decision was entirely theirs.

    この表現を使う理由: Theirs is written as a single word with no apostrophe.

自分で試す

Which form is correctly written?

答えを見る

答え: The choice is theirs.

Possessive pronouns never use apostrophes, making theirs the only correct spelling.

Hear Stress and Vowel Shifts in Natural Speech

In spoken English, possessive adjectives usually carry lighter stress than the nouns they introduce. In contrast, possessive pronouns receive full sentence stress because they carry the central contrast of the thought. Pronouncing yours, hers, ours, and theirs with clear final consonants ensures your listener catches who owns what.

  • That blue umbrella is ours.

    この表現を使う理由: The word ours carries final emphasis and a distinct vowel sound.

  • Is that lunch box yours?

    この表現を使う理由: Yours receives stress at the end of the question.

自分で試す

Why do possessive pronouns usually carry stronger spoken stress than possessive adjectives?

答えを見る

答え: They replace the whole noun phrase and carry key information.

Because possessive pronouns stand in place of the entire noun phrase, they highlight the owner and receive sentence stress.

Confirm Shared Ownership Without Clumsy Phrasing

In shared workspaces or apartments, items often move around quickly. When someone asks whose item is on a counter, answering with a crisp pronoun resolves confusion immediately. Practice pairing a clear noun identification with a decisive possessive pronoun to keep daily workplace or home conversations smooth.

  • These markers belong to our floor, so they are ours.

    この表現を使う理由: Ours quickly establishes team ownership of the markers.

  • The laptop on the side table is hers, not mine.

    この表現を使う理由: Hers and mine contrast two possible owners clearly.

自分で試す

A coworker points to a notebook and asks, 'Is this notebook for the marketing team?' If you represent that team, what is the most concise reply?

答えを見る

答え: Yes, it is ours.

Using the possessive pronoun ours answers concisely without repeating the noun.

「Possessive Pronouns: Choose the Right Form」に関する質問

Can I use 'its' as a standalone possessive pronoun?

In standard modern English, 'its' is normally used as a possessive adjective before a noun; rare independent uses occur in phrases such as of its own. You do not say 'The bowl is its'. Instead, name the noun again or restructure the sentence to say 'The bowl belongs to the cat' or 'That is its bowl'.

The bird flew back to its nest.

That nest is its home.

Why is there no apostrophe in words like yours, hers, or ours?

Nouns use apostrophes to show possession, like Sarah's book or the company's goal. Possessive pronouns are already inherently possessive by definition. Adding an apostrophe turns the word into an incorrect form or a contraction, so yours, hers, ours, and theirs never take apostrophes.

The green umbrella is yours.

Those concert tickets are ours.

How do I choose quickly between 'my' and 'mine' during a conversation?

Check whether the possessive introduces a noun phrase, which may contain adjectives. If you are about to say the noun, use 'my', as in 'my coat'. If you already said the noun earlier and do not want to say it again, use 'mine', as in 'That coat is mine'. A possessive pronoun never comes right before the noun it owns.

My phone is on the counter.

The phone on the counter is mine.

What is the difference between 'their' and 'theirs'?

Use 'their' before a noun phrase to indicate group possession, such as 'their car' or 'their opinion'. Use 'theirs' when the noun has already been stated and you want to avoid repetition. Remember that 'theirs' already ends in s and never takes an apostrophe.

Their flight leaves at noon.

Our flight is delayed, but theirs is on time.

最後に確認

これを覚えましょう

Check whether a noun follows your possessive word. If the possessive introduces a noun phrase, choose my, your, his, her, its, our, or their. If the noun has already been established and stands earlier in the sentence, use mine, yours, his, hers, ours, or theirs. Keep apostrophes off all possessive pronouns.
