our vs your

Use our when the owner includes the speaker (I/we). Use your when the owner is the person or people you're addressing (you).

Below: a concise rule, clear examples for work, school, and casual contexts, quick rewrite patterns you can paste, a proofreading checklist, and related grammar traps to watch for.

Quick answer

our = possession that includes the speaker (we/ours). your = possession of the addressee (you/yours).

our → the speaker + others (our team, our file)
your → the person you're addressing (your report, your phone)
If ownership is unclear, name the owner (the team's report) or use a neutral noun (the document).

Core explanation: who owns it?

Both our and your are possessive determiners that come before a noun. Ask: who is the owner in this sentence - the speaker (I/we) or the addressee (you)?

Quick editing test: substitute we/ours and you/yours aloud. If we/ours fits naturally, use our; if you/yours fits, use your.

Basic structure: our + noun (our deadline) | your + noun (your deadline).
For mixed audiences or unclear ownership, name the owner to remove ambiguity (the client's invoice, the design team's mockup).

Examples: six common wrong/right pairs

Each pair shows a typical slip with a brief note on why the correction matters.

Wrong: "Please review our report before you submit." - (If addressing the person who owns the report.)
Right: "Please review your report before you submit." - Use your when the recipient owns the report.
Wrong: "Our account has an overdue balance." - (If speaking to a customer about their account.)
Right: "Your account has an overdue balance." - The customer owns the account.
Wrong: "Can you forward your notes to the group?" - (If the speaker and addressee both wrote notes.)
Right: "Can you forward our notes to the group?" - Use our when notes belong to the speaker plus others.
Wrong: "We updated your schedule for the team meeting." - (If the speaker updated the speaker's team schedule.)
Right: "We updated our schedule for the team meeting." - Use our when the schedule belongs to the speaker's group.
Wrong: "Please confirm our phone number." - (If asking a customer to confirm their number.)
Right: "Please confirm your phone number." - The customer owns the phone number.
Wrong: "Your decisions affect our progress." - (If the speaker is part of the same group making decisions.)
Right: "Our decisions affect our progress." or "Your decisions affect the project's progress." - Choose pronouns or name the owner to clarify.

How to rewrite: practical patterns to fix ownership errors

When you're unsure, apply one of these quick rewrites to make ownership explicit.

Name the owner: "the team's report", "the client's invoice", "the student's file".
Use a neutral noun: "the document", "the file", "the application".
Shift to role-based phrasing: "your team's schedule", "the instructor's notes".
Make the agent explicit: "We'll send the invoice for your account tomorrow."
Avoid possessive with passive: "The report has been uploaded."

Rewrite examples:

Original: "Please review your draft." → If the instructor means a draft they prepared: "Please review the draft I shared."
Original: "Our form needs signatures." → If the form belongs to the other party: "Your form needs signatures."
Original: "Can you check our schedule?" → To name the owner: "Can you check the team's schedule?"

Memory trick and quick proofreading checklist

Fast checks that catch most swaps:

Substitute test: replace the possessive with "ours" and "yours". If "ours" fits, use our; if "yours" fits, use your.
Ask two questions: Who is speaking? Who is being addressed? Who owns the noun?
If answers are unclear, name the owner or use "the" + noun.
Read the whole sentence aloud - context usually fixes the choice immediately.

Similar mistakes, spacing, hyphenation, and other grammar pitfalls

Watch these related confusions and formatting traps.

you're vs your: you're = you are; your = possessive. Wrong: "Your going to be fine."
Right: "You're going to be fine."
its vs it's: its = possessive; it's = it is. Wrong: "The dog wagged it's tail."
Right: "The dog wagged its tail."
their/there/they're: choose based on meaning-possession/place/contraction.
Spacing/hyphenation: keep the possessive and noun together. Don't write extra spaces or insert hyphens between them (write "your phone", not "your - phone").
Possessive placement: avoid misplacing which noun the possessive modifies. If unclear, reorder: "the client's payroll report" instead of "the client payroll report."

FAQ

Can I use our when writing to a group that includes me and the reader?

Yes. If you and the reader are both members of the same group (for example, a club post: "Our meeting is at 6"), our is correct.

Is your always right in customer emails?

Usually use your when referring to customer-owned items. Use our for company-owned items or shared resources.

What's the fastest way to check my sentence?

Swap in "ours" and "yours" or say "we" and "you" aloud. If "ours" or "we" fits the speaker, use our; if "yours" or "you" fits, use your.

Should I avoid both our and your if I'm unsure?

Yes-when ownership is unclear, rewrite to name the owner (the team's report) or use a neutral noun (the document, the application).

My grammar checker flags our vs your-should I trust it?

Grammar tools help but sometimes miss context. Use them plus the substitution test; if the checker suggests your but you mean our (you + me), keep our.
