your (you're)

Your and you're sound identical but serve different roles: your is possessive; you're is the contraction of you are. Quick check: can you expand it to "you are"? If so, you're. If not, your.

Fast rule

your = possessive adjective (shows ownership). you're = contraction of you are.

your + noun → your report, your phone, your idea.
you're = you are + (adjective / verb phrase): you're welcome, you're late.
Substitution test: replace the word with "you are." If the sentence still makes sense, use you're; otherwise use your.

Core grammar: how to decide

Your modifies a noun; you're stands for the subject + verb you are. Swapping them changes meaning or makes the sentence ungrammatical.

If a noun follows immediately, it's almost always your: your plan, your notes.
If you can expand to "you are" (you are + ...), use you're: you're excited, you're meeting us.

Wrong: Your going to love this.
Right: You're going to love this.
Wrong: I filed you're report.
Right: I filed your report.

Spacing, apostrophes, and hyphenation - what to watch for

You're always needs an apostrophe (you + ' + re). Never write you re or your' for the contraction. Your never takes an apostrophe for possession (your's is wrong).

Hyphenation doesn't change these words. Only break words across lines for typesetting; that doesn't alter spelling or usage.

Wrong: you re, your', your's
Right: you're (contraction) and your (possessive)
If spellcheck flags both words as valid, use the substitution or noun test rather than relying on spelling alone.

Wrong: you re not allowed to change the settings.
Right: you're not allowed to change the settings.
Wrong: Is that your's?
Right: Is that yours?

Memory tricks that actually work

Two quick mental tests will catch most errors without slowing you down.

Substitute test: Replace the word with "you are." If it fits, write you're.
Noun test: If it sits before a noun, write your.
Sound test: Say the sentence aloud. If you naturally say "you are," use you're; if you say "your X," use your.

Example: "You're (= you are) welcome" vs "your welcome" (only correct if welcome is a noun being possessed, which is rare).
Example: "your notes" → noun after → your.

Step-by-step editing routine (3 quick checks)

Spot "your/you're" in a draft? Run these in order.

1) Substitute: Can you expand it to "you are"? If yes → you're.
2) Next word: Is it a noun? If yes → your.
3) Read aloud: Does it sound like "you are" or "your + noun"?

Rewrite:
Original: "Your submitting the report tomorrow?" → "You're submitting the report tomorrow?"
Rewrite:
Original: "Please review you're comments." → "Please review your comments."
Rewrite:
Original: "Your not ready to present." → "You're not ready to present."

Try your own sentence

Test the whole sentence rather than the phrase by itself-context often makes the correct choice obvious.

School examples - teacher and student lines

Casual examples - texts and social posts

Contractions are fine in informal writing, but the wrong word still distracts.

Casual - Wrong: Your kidding me!
Casual - Right: You're kidding me!
Casual - Wrong: I love you're new profile pic.
Casual - Right: I love your new profile pic.
Casual - Wrong: Are your coming tonight?
Casual - Right: Are you coming tonight? (Or: You're coming tonight?)

Similar mistakes to watch for

Use the same substitution and possession checks on these pairs.

its vs it's - its = possessive; it's = it is / it has.
their vs they're vs there - their = possessive; they're = they are; there = place or introductory.
whose vs who's - whose = possessive; who's = who is / who has.

Wrong: Its been a long day.
Right: It's been a long day.
Wrong: Their late to the meeting.
Right: They're late to the meeting.

FAQ

Is it your or you're before a noun?

Use your before a noun: your idea, your phone, your presentation.

Quick trick to remember which to use?

Replace it with "you are." If the sentence still makes sense, use you're; if not, use your.

When is "your welcome" correct?

"Your welcome" is only correct if "welcome" is a noun being possessed (rare). Most of the time you want "you're welcome" or simply "welcome."

Will spellcheck catch this error?

Not reliably. Spellcheck treats both words as valid. Use a grammar checker or the substitution/noun test for context-aware decisions.

Should I avoid contractions in formal writing?

Contractions like you're are grammatically correct, but many formal styles prefer "you are" spelled out for tone. Aim for clarity and consistency.

Quick habit to avoid future errors

Add the substitution test to your editing routine; it takes a second and prevents confusion. When unsure, run the three quick checks or paste a sentence into a grammar tool for context-aware suggestions.
