1. Introduction

"His leaving surprised everyone" and "Him leaving surprised everyone" are both genuinely used by native speakers, but they belong to different registers. This is a small, precise point that matters most in formal writing, exactly the kind of detail that separates confident, natural English from merely correct English.

2. Quick Summary

⚡ Possessive + Gerund at a Glance

FormalPossessive + gerund: His leaving surprised us. I appreciate your helping me.
InformalObject pronoun + gerund: Him leaving surprised us. I appreciate you helping me.
With namesJohn's arriving late annoyed everyone.
When it mattersFormal and academic writing; less strict in everyday speech

3. The Rule

When a gerund (the -ing form used as a noun) has its own subject, that subject can take the possessive form, treating the whole gerund phrase like a noun belonging to that person.

StructureExample
Possessive pronoun + gerundHis leaving surprised us. Her singing is beautiful.
Possessive noun ('s) + gerundJohn's arriving late annoyed everyone.

4. Formal vs Informal Use

In practice, most native speakers default to the object pronoun form in everyday conversation, reserving the possessive form for careful, formal writing.

RegisterExample
Formal / writtenI was surprised by his leaving so suddenly.
Informal / spokenI was surprised by him leaving so suddenly.
💡
Both are genuinely acceptable This isn't a case of one being wrong, native speakers use the object pronoun version constantly in speech. The possessive form is a mark of formal register, not a strict grammatical requirement everywhere.

5. Common Fixed Expressions

ExpressionExample
appreciate + possessive + gerundI appreciate your helping me with this.
mind + possessive + gerundWould you mind my asking a question?
excuse/forgive + possessive + gerundExcuse my interrupting, but...

6. Common Mistakes

❌ Incorrect✅ CorrectWhy
Would you mind me to ask a question?Would you mind my asking a question?This fixed expression needs the possessive + gerund, not "to + base verb."
I appreciate you to help me.I appreciate your helping me. / I appreciate you helping me."Appreciate" is followed by a gerund, not a to-infinitive.
John arriving's late annoyed everyone.John's arriving late annoyed everyone.The possessive 's attaches to the name itself, before the gerund, not mid-phrase.
