Verb with 's

People sometimes add an apostrophe + s to a subject because they see verbs ending in -s (he walks) and assume the apostrophe belongs there. It doesn't. 's marks possession (John's book) or contracts "is/has" (John's = John is / John has). It is not the third-person singular verb ending.

Below: a tight rule, clear examples across contexts, many ready-to-use rewrites, quick proofreading checks, and memory tricks to fix sentences like "John's dances gracefully."

Short answer

Don't put an apostrophe-s before a finite verb. Use the plain -s on the verb (John dances) or use 's only when it stands for "is" or "has" (John's = John is/has) and the rest of the sentence matches that contraction.

Wrong: John's dances gracefully. (apostrophe makes John's possessive or a contraction)
Right: John dances gracefully. (third-person singular present)
If you meant "John is": John is dancing now or John's dancing now (contraction before a participle).

Core explanation: what 's does and why verbs don't take it

's has two jobs: show possession (John's phone) or replace letters in a contraction (John's = John is / John has). It never marks the present-tense -s on verbs.

Third-person singular verbs add an -s without an apostrophe: he walks, she sings, the system updates.

Apostrophe = ownership or omitted letters.
Plain -s on verbs = subject-verb agreement (no apostrophe).
Spot 's before a finite verb? Ask: did the writer mean "is/has" or possession? If not, remove the apostrophe.

Real usage and tone: when a contraction is okay

Contractions like "John's" are common in speech and informal writing when they replace "John is" or "John has." They are correct only if the sentence reads naturally after expansion.

Possessive 's followed by a noun is a different meaning: "John's dance" means the dance belongs to John, not that he performs it.

Acceptable contraction: "John's going to the store." (John is going)
Acceptable possessive: "John's performance" (noun follows the possessive)
Not acceptable: "John's dances" when you mean "John dances."

Rewrite help: ready-to-use fixes and many rewrites

When you see "X's + finite verb" (e.g., "John's dances"), choose one of three fixes: remove the apostrophe, expand the contraction, or change structure to show possession.

Remove the apostrophe if the verb should carry the -s: John's dances → John dances.
Expand the contraction if you meant "is/has": John's dancing now → John is dancing now.
Rephrase for possession: John's dancing → John's dance (if the dance is a noun) or John's dancing style.

Rewrite:
Original: John's dances gracefully. → Fix: John dances gracefully.
Rewrite:
Original: John's planning to attend. → Fix: John is planning to attend. (or John plans to attend.)
Rewrite:
Original: John's finished the report. → Fix: John has finished the report.
Rewrite:
Original: The manager's approves next week. → Fix: The manager approves next week. (or The manager will approve next week.)
Rewrite:
Original: The student's submits late. → Fix: The student submits late. (or The student's submission is late.)
Rewrite:
Original: Anna's trains every morning. → Fix: Anna trains every morning. (or Anna is training every morning.)
Rewrite:
Original: My friend's calls after dinner. → Fix: My friend calls after dinner.
Rewrite:
Original: It's updates the system automatically. → Fix: It updates the system automatically. (it's = it is would be wrong here)

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

Memory tricks: short tests to stop the error

Fast checks to use when you spot an apostrophe before a verb.

Three-question test: 1) Can 's mean "is" or "has" here? 2) Is the next word a participle or auxiliary? 3) If not, remove the apostrophe.
Read aloud expanding the contraction: "John is dances" sounds wrong - change to "John is dancing" or "John dances."
Mnemonic: "Apostrophe = ownership or omission." If you're not showing ownership or missing letters, drop the apostrophe.

Usage: Test phrase: "John's paints the fence." → Say "John is paints the fence" (wrong). So drop the apostrophe: "John paints the fence."

Similar mistakes to watch for

Confusing contractions, possessives, and plurals often go together with the 's-before-verb error.

it's vs its: it's = it is / it has; its = possessive.
Don't use apostrophes for plurals: write three CDs, not CD's.
Don't add 's to pronouns: hers's is wrong; use hers or she's (she is).

Wrong: The report is late - its' not ready.
Right: The report is late - it's not ready. (or The report is late - it is not ready.)

Hyphenation and spacing: tiny details that hide the error

Poor spacing or pasted typography can mask the problem. Fix spacing and check the apostrophe placement.

Never put a space before an apostrophe: John's (correct) vs John 's (wrong).
Curly vs straight apostrophes don't change grammar but can appear when copying text - focus on words, not glyph style.
Hyphens belong to compound modifiers (well-known rule) and do not replace apostrophes.

Usage: Bad spacing: John 's dances gracefully. → Fix spacing and grammar: John dances gracefully.

Fix your own sentence: quick checklist

Four fast steps when you see an apostrophe before a verb.

Step 1: Expand 's to "is/has": does the sentence make sense? If yes, keep the contraction but check verb form (John's going = John is going).
Step 2: If expansion fails, remove the apostrophe and check subject-verb agreement (John dances).
Step 3: If the meaning is possessive, ensure a noun follows the possessive (John's dancing style).
Step 4: Read aloud. If it sounds like two verbs in a row ("John is dances"), it's wrong.

Usage: Checklist in action: "The team's approves the plan." → Expand: "The team is approves" (no); Remove apostrophe: "The team approves the plan." (yes)

FAQ

Why is "John's dances" wrong?

's marks possession or contracts "is/has." It doesn't mark the third-person -s on verbs. If you mean John performs the action, write "John dances." If you mean "John is dancing," write "John is dancing" or "John's dancing now."

When can I use "John's" before a verb?

Only when 's stands for "John is" or "John has" and the rest of the sentence matches that meaning (e.g., "John's going" = "John is going"). It should not come before a finite verb that already takes -s (e.g., "dances").

How do I fix sentences like "The team's meets"?

Remove the apostrophe: "The team meets." The apostrophe incorrectly suggests possession or contraction; verbs in third-person singular simply use -s.

Is "Johns dances" ever correct without an apostrophe?

No for a single person. "Johns dances" would imply the proper name "Johns" (pluralized surname) followed by a verb, which is rarely correct. For multiple Johns, write "Johns dance." For one John, write "John dances."

Will a grammar checker catch this?

Most grammar checkers flag an apostrophe before a finite verb and suggest removing it or expanding the contraction. Always confirm the suggested change matches the sentence's intended meaning.
