Quick answer
Use "He is" or "He's" for the verb and "his" for possession. Never write "He his" as a verb phrase.
- He's = he is OR he has (contraction) - needs an apostrophe.
- His = possessive adjective: his coat, his idea.
- Fast fix: decide whether the sentence needs a verb (use He is/He's) or ownership (use his).
Core explanation: contractions, possession, spacing
Apostrophes mark contractions. "He's" shortens "he is" or "he has." "His" is a possessive adjective and never replaces a verb. Putting them together as "He his" normally mixes two different parts of speech.
Spacing and hyphenation rarely apply: this is not a hyphenation issue but a substitution of a verb with a possessive. If you hear the phrase, remember the written forms are distinct.
- Contraction rule: Replace "he is" with "he's" only when you want the contracted form.
- Possessive rule: Use "his" before a noun to show ownership (his book, his idea).
- Grammar check: If a verb is required, read the sentence with "he is" to see whether it makes sense.
Why this error happens
The mistake usually comes from hearing speech, typing quickly, or from an autocorrect/keyboard replacement that misfires.
- Sound-based guessing: spoken "he's" can be misread as two words.
- Typing speed or sloppy editing.
- Autocorrect or replacement rules that map abbreviations incorrectly.
- Overcorrection when trying to avoid an apostrophe.
Real usage: correct examples in context
Seeing correct forms in normal sentences helps you spot the error.

- Work: If he's ready, we'll start the demo at 2 p.m.
- Work: His report arrived just before the meeting.
- School: He is writing the conclusion for the essay tonight.
- School: He's completed three of the five practice problems.
- School: His sources are listed on the bibliography page.
- Casual: He's running late-grab dinner without him.
- Casual: He is coming over after work.
- Casual: His bike needs a new tire.

How to fix sentences (rewrite help)
Don't just swap words-check tone and flow. Small rewrites often sound more natural than a literal replacement.
- Step 1: Identify whether the sentence needs a verb or a possessive.
- Step 2: Insert the standard form ("He is" / "He's" / "his").
- Step 3: Read the whole sentence to confirm clarity and tone.
- Rewrite example 1: Original: This plan is He his going if everyone stays late.
Rewrite: This plan is He is going if everyone stays late. - Rewrite example 2: Original: The assignment feels He his going now.
Rewrite: The assignment feels He is on track now. - Rewrite example 3: Original: He his taking the lead on this.
Rewrite: He's taking the lead on this.
A simple memory trick
Link the form to meaning: picture "He is" as the action unit and "his" as ownership. When you hear "he's," imagine the apostrophe-without it you need either "he is" or a possessive noun after "his."
- Search your drafts for "he his" and fix in bulk.
- Train your eye by reading sentences aloud: verbs sound like actions ("he is..."), possessives need a noun ("his book").
- Set a keyboard shortcut to expand "hes" into "he's" or "he is" if needed.
Similar mistakes to watch for
Once one spacing or contraction error appears, related errors often follow.
- its / it's
- your / you're
- their / they're / there
- mixing verb forms and possessives (e.g., "she her" instead of "she is")
FAQ
Is "he his" ever grammatically correct?
Not as a verb phrase. You can have both words in a sentence serving different roles-e.g., "He said his name was John"-but "He his" next to each other where a verb belongs is incorrect.
How do I stop autocorrect from turning "he's" into "he his"?
Remove any keyboard replacements that create the wrong mapping and add a replacement that expands your intended form ("hes" → "he's" or "he is"). Check custom dictionaries and text-expansion rules.
When should I use "He is" instead of "He's"?
Use "He is" in formal writing, for emphasis, or when clarity matters. Use "He's" in casual writing, dialogue, or conversational email. Avoid contractions in formal reports and essays unless style permits them.
What's the fastest edit to fix every instance?
Find the exact string "he his" and run the expand-test: if "he is" or "he's" fits, replace; if possession fits, restructure the sentence to start with "His" or add the noun after "his."
Are there other pronoun errors I should watch for?
Yes. Its/it's, your/you're, and their/they're/there are frequent siblings. Expand contractions mentally and substitute a possession phrase ("belongs to...") to check which form fits.
One quick habit to build
Before you send or submit, do a three-second find for "he his" and run the expand-test on any hits. Small, targeted checks and a grammar tool that flags missing apostrophes will catch this error repeatedly.
