Missing possessive: This weeks (week's) meeting

Missing possessive apostrophes make sentences unclear or unprofessional. Use these short rules, many wrong/right pairs, and ready rewrites to spot and fix errors quickly.

If you need a quick answer, scan the examples, find a matching pattern, and copy the rewrite that fits your sentence.

Quick fix

Most singular owners: add 's (the editor's note). Plural owners ending in s: add only an apostrophe (the editors' meeting). Irregular plurals add 's (the children's books). Its = possessive pronoun (no apostrophe); it's = it is / it has.

Singular: noun + 's - the manager's email.
Plural ending in s: noun + ' - the managers' meeting.
Plural not ending in s: noun + 's - the men's room.
Contractions: it's = it is / it has; its = belonging to it.

Core rules: when to add the apostrophe

Apostrophes mark possession or replace missing letters. For possession: singular nouns take 's; plural nouns ending in s take only '; irregular plurals take 's. Possessive pronouns (its, yours, ours, theirs) never use an apostrophe.

Singular: add 's - the student's laptop.
Plural ending in s: add ' - the students' lounge.
Irregular plural: add 's - the children's teacher.
Pronouns: its (possessive) vs it's (it is/has).

Wrong → Right: The boss office is closed. → The boss's office is closed.
Wrong → Right: The restaurants patio opened. → The restaurant's patio opened. (one restaurant) or The restaurants' patio opened. (multiple)

Spacing and punctuation around the apostrophe

Never add spaces around an apostrophe: the cat's bowl (not the cat 's bowl). Periods and commas follow the possessive normally: I returned Lisa's book. When a possessive ends a sentence, keep the apostrophe before the period: That's Mark's.

No spaces: the teacher's desk (not the teacher 's desk).
Punctuation after the possessive: I used Anna's, then I left.
In quoted material follow your style guide for punctuation order (American vs British).

Wrong → Right: the cat 's food bowl → the cat's food bowl
Wrong → Right: We saw Johns. → We saw John's.

Common wrong/right pairs (high-frequency errors)

Scan for an ownership relationship or a contraction. If you can naturally say "belongs to," use a possessive form.

Wrong → Right: My moms recipe is the best. → My mom's recipe is the best.
Wrong → Right: The teachers lounge is near the gym. → The teachers' lounge is near the gym.
Wrong → Right: Its been a long day. → It's been a long day.
Wrong → Right: The womens team won. → The women's team won.
Wrong → Right: Aaron shoes are by the door. → Aaron's shoes are by the door.
Wrong → Right: The companys policy changed. → The company's policy changed.
Wrong → Right: Apples prices fell. → Apples' prices fell. (if referring to many apple varieties) or Apple prices fell. (if brand)

Work writing: emails, reports, and labels

Subject lines, headers, and slide labels often lose apostrophes. Fix these to keep documents clear and credible.

Decide whether a label is plural or possessive: Managers meeting vs Manager's meeting.
Be consistent across menus, headers, and forms.

Usage: Wrong: The teams schedule is updated. →
Right: The team's schedule is updated.
Usage: Wrong: Clients feedback was positive. →
Right: Clients' feedback was positive.
Usage: Wrong: Managers decision will be shared. →
Right: Manager's decision will be shared. (Or Managers' decision if multiple managers decided.)

School and academic examples

Small punctuation errors can affect grades and perceived professionalism. Check assignment titles and author attributions carefully.

Confirm group vs single-author references in titles and headers.
Follow your citation style but keep possessives clear.

Usage: Wrong: Students essay was submitted late. →
Right: Student's essay was submitted late. (One student) or Students' essay (group).
Usage: Wrong: The teachers instructions were unclear. →
Right: The teacher's instructions were unclear. (Or teachers' if referring to all teachers.)
Usage: Wrong: The childrens book is on the shelf. →
Right: The children's book is on the shelf.

Try your own sentence

Test the whole sentence, not just a phrase. Context usually makes the correct form clear.

Casual writing: texts, social posts, and quick notes

People skip apostrophes in quick messages, but public posts and captions benefit from clear possessives to avoid confusion.

Keep contractions casual but preserve possessives for names and businesses.
A missing apostrophe in a scanned headline can change meaning.

Usage: Wrong: Johns going to the concert. →
Right: John's going to the concert.
Usage: Wrong: Moms birthday dinner tonight! →
Right: Mom's birthday dinner tonight!
Usage: Wrong: The bands new song is fire. →
Right: The band's new song is fire.

Rewrite help: three quick steps and ready templates

Fix a sentence in three steps: (1) identify the owner and the thing owned, (2) test with "belongs to", (3) apply 's or '. If ambiguous, rewrite with "of" or reorder the sentence.

Template A (single owner): [owner]'s [thing] - the editor's note.
Template B (multiple owners): [owners]' [thing] - the editors' meeting.
Template C (avoid ambiguity): the [thing] of [owner] - the schedule of the team.

Rewrite:
Wrong: The teachers lounge needs new chairs. → The teachers' lounge needs new chairs.
Rewrite:
Wrong: Its color is brighter than expected. → Its color is brighter than expected. (Correct - no apostrophe for possessive pronoun.)
Rewrite:
Wrong: Customers complaints were high. → Customers' complaints were high. / The complaints of customers were high.

Real usage and tone: style choices, decades, and hyphenation

Some choices are stylistic: Charles's vs Charles'. Pick a form and be consistent. For decades, use 1990s (no apostrophe) unless you mean a possessive.

Hyphenation usually isn't affected by apostrophes, but possessives inside compound modifiers can look awkward; prefer an of-construction if readability suffers.

Names ending in s: choose 's or ' and stay consistent (James's album or James' album).
Decades: 1990s revival (no apostrophe) vs the 1990s' legacy (possessive case).
If a compound modifier is clumsy with a possessive, rewrite: the team's on-site policy → the on-site policy of the team.

Usage: Style: Charles's book (Chicago) vs Charles' book (journalism). Either is fine if consistent.
Usage: Wrong: The 1980's music revival. →
Right: The 1980s music revival.

Memory tricks and similar mistakes to watch for

Use the "belongs to" test: if you can insert "belongs to" naturally, you probably need a possessive. Use the "it is" test for it's vs its.

Watch for plural vs possessive confusion, possessives with decades/abbreviations, and dropped apostrophes in headings and labels.

Mnemonic 1: "Belongs to" → use a possessive (the dog's leash = the leash belongs to the dog).
Mnemonic 2: Expand contractions - it's = it is/has; its = possessive.
Check headings, forms, and menus first; they get missed most often.

Wrong → Right: Wrong: Its tail is long. →
Right: Its tail is long. (Correct - no apostrophe.)
Wrong → Right: Wrong: The 1990s' culture was unique. →
Right: The 1990s culture was unique.
Wrong → Right: Wrong: Johns report was accepted. →
Right: John's report was accepted.

FAQ

When should I use its versus it's?

Use it's only for "it is" or "it has." Use its (no apostrophe) for possession: The company adjusted its policy.

Do I add 's for names that already end with s (e.g., James)?

Both James's and James' are used. Many style guides prefer James's; choose one form and stay consistent across the document or team.

How do I form possessives for plural nouns that don't end in s?

Add 's for irregular plurals: the children's playground, the men's restroom.

Is it acceptable to drop apostrophes in casual messages?

In private texts, yes. Avoid dropping possessives in public posts, subject lines, or professional messages where clarity matters.

What's a fast way to catch missing possessive apostrophes?

Read sentences aloud and test "belongs to" or "it is" conversions. Use a grammar checker to highlight likely possessive errors and suggested rewrites.

Want a quick check?

If you're unsure, paste your sentence into a grammar checker or apply the three-step rewrite: identify owner, test with "belongs to", apply the rule. Copy the example that matches your case and swap in your owner/thing.
