Writers often add an apostrophe where it doesn't belong: "The cat's are playing" instead of "The cats are playing." That stray apostrophe can turn a simple plural into a possessive or into a contraction, changing the meaning and sounding wrong on the page.
Below are clear rules, quick checks, and many real examples so you can spot and fix redundant apostrophes fast-at work, at school, and in casual messages.
Quick take
Apostrophes mark possession (the cat's toy) or contractions (it's = it is). They do not form regular plurals. Use "cats," not "cat's," when you mean more than one cat.
- Plural: cats, dogs, reports (no apostrophe).
- Singular possessive: cat's (the cat's toy).
- Contraction: it's = it is / it has (only when that meaning fits).
- Small exception: plurals of single letters (mind your p's and q's).
How apostrophes work
Ask two quick questions when you see an apostrophe: 1) Does it expand to "is" or "has"? 2) Does it answer "whose?" If neither, you probably don't need an apostrophe.
- If "'s" can expand to "is/has" and the sentence still makes sense, it's a contraction: "The cat's outside" = "The cat is outside."
- If the phrase answers "whose?", use possessive: "the cat's collar" (whose collar?).
- If you mean more than one item or person, use a plural with no apostrophe: "the cats are hungry."
Is "The cat's are" ever correct?
Almost never. "The cat's" either shows ownership or contracts "the cat is." If you mean two or more cats as the subject, write "The cats are."
When you see a noun followed immediately by a verb (noun + 's + verb), check whether the writer intended a contraction or a plural subject.
Spacing and hyphenation pitfalls
Some mistakes come from spacing: writers split or join words incorrectly, then add an apostrophe out of uncertainty. Hyphenation issues are related but separate-use a hyphen for compounds when style or meaning requires it, not to mark plurals.
- Don't use an apostrophe to pluralize compound terms: 1990s, not 1990's (unless showing possession).
- Check whether a phrase is normally one word, hyphenated, or two words; fix spacing first, then check apostrophes.
Why writers add redundant apostrophes
These errors come from relying on sound, quick typing, or overcorrection. When we hear language more than we see it, spelling decisions can go wrong.
- Sound-based guessing (writing what it sounds like).
- Rushing through drafts and skipping a reread.
- Overcorrecting-trying to be careful but choosing the wrong rule.
Real usage: work, school, casual
Seeing correct forms in context helps you spot the wrong ones fast. Below are short, natural examples from three settings.
- Work: The reports are due Monday; the teams are already reviewing them.
- Work: The manager's feedback arrived this morning. (possession)
- Work: If the servers are down, the site's traffic drops quickly.
- School: The essays are graded and ready for pickup.
- School: The student's answer was thoughtful. (possession)
- School: We're revising the paper before the deadline. (contraction)
- Casual: Your idea sounds fun-are you joining tonight?
- Casual: It's cold outside; grab a jacket. (contraction)
- Casual: We're having fish and chips for dinner.
Wrong vs right examples you can copy
These pairs show the mistake and the correct fix. Copy the right lines or paste them into your drafts for quick replacements.
- Wrong: The cat's are playing in the garden.
Right: The cats are playing in the garden. - Wrong: Your going to love this.
Right: You're going to love this. - Wrong: I think its going to rain today.
Right: I think it's going to rain today. - Wrong: We're having fish and chip's for dinner.
Right: We're having fish and chips for dinner. - Wrong: The report's are on the shared drive.
Right: The reports are on the shared drive. - Wrong: Mind your p's and q's.
Right: Mind your p's and q's. (apostrophe allowed for single letters)
How to fix your own sentence
Fixing apostrophe errors is a three-step routine: identify meaning, apply the standard form, and reread for tone and clarity.
- Step 1: Identify whether you mean possession, contraction, or plural.
- Step 2: Replace the incorrect form with the correct possessive, contraction, or plain plural.
- Step 3: Reread the full sentence to ensure natural flow; sometimes a short rewrite is cleaner than a literal swap.
- Original: This plan is The cat if everyone stays late. Fix: This plan works if everyone stays late. (rewrite for clarity)
- Original: The assignment feels The cat now. Fix: The assignment feels overwhelming now. (rewrite to avoid awkward phrasing)
- Original: Is that The cat this afternoon? Fix: Is that the schedule for this afternoon? (clarify subject)
A simple memory trick
Link the form to meaning, not sound. If you can answer "whose?" use 's; if you can expand to "is" or "has" accept the contraction; otherwise use a plain plural.
- Visualize the plural as a unit: "cats" (no apostrophe).
- Scan for noun + 's + verb-those are the spots that often need checking.
- Search your draft for common offender patterns (your/you're, its/it's, noun's followed by a verb) and fix them in bulk.
Similar mistakes to watch for
Fixing one apostrophe error often reveals related issues nearby. Do a quick sweep once you correct one instance.
- Misplaced spaces (e.g., "in to" vs "into").
- Hyphen confusion in compound adjectives (well-known vs well known).
- Verb-form errors that look like punctuation mistakes.
- Mixing possessive and plural forms in the same paragraph.
FAQ
Is "The cat's are" ever correct?
Practically never. "The cat's" means possession or contraction. If you mean multiple cats as the subject, use "The cats are."
How can I check quickly whether to use an apostrophe?
Try three quick checks: expand "'s" to "is/has"; ask "whose?"; ask whether you mean plural. If none apply, drop the apostrophe.
Do spellcheckers catch redundant apostrophes?
Not always. Spellcheckers may not flag "cat's" vs "cats" because both are valid tokens. Use the quick expand/possess/count tests or a grammar tool that checks context.
Are apostrophes ever allowed in plurals?
Generally no for regular nouns. One exception is pluralizing single letters or symbols where an apostrophe improves readability (e.g., p's and q's).
What's the fastest edit routine before sending a message?
Scan for noun + "'s" followed immediately by a verb. Ask whether you mean "is/has" or a plural subject. Correct those and glance over other common pairs (your/you're, its/it's).
