How to Use the GrammarVista.com Grammar Checker
- Write or paste your text. Start with a short email, paragraph or essay section.
- Run the check. The tool scans your text for grammar, spelling and punctuation issues.
- Read each suggestion. Do not click “accept” automatically. Read the reason behind each correction.
- Apply what fits your meaning. No tool understands your intent perfectly, so you decide.
- Re-read the final version aloud. Reading aloud catches awkward phrasing that software can miss.
- Learn from repeated mistakes. If the same error appears often, study that rule once and it will stop appearing.
Tips for Better Results
- Check short sections at a time so you can focus on each correction.
- Remove sensitive details, such as passwords or private client information, before you paste any text into an online tool.
- Set the right tone before checking: formal for work, relaxed for blog posts.
- Use the checker as a second pair of eyes, not as a replacement for your own judgment.
Most Common Grammar Mistakes in American English
| Mistake | Correct Version | Quick Rule |
|---|---|---|
| Its / It’s | “It’s raining. The dog wagged its tail.” | It’s = it is or it has. Its shows ownership. |
| Your / You’re | “You’re late. Where is your bag?” | You’re = you are. Your shows ownership. |
| Affect / Effect | “Weather can affect sales. The effect was small.” | Affect is usually a verb. Effect is usually a noun. |
| Then / Than | “She is taller than him. Finish, then leave.” | Than compares. Then shows time or order. |
| Fewer / Less | “Fewer cars, less traffic.” | Use fewer for countable things and less for uncountable ones. |
| Who / Whom | “Who called? To whom did you speak?” | Who is the subject. Whom is the object. |
| Comma splice | “I was tired, so I left.” | Do not join two full sentences with only a comma. |
| Their / There / They’re | “They’re over there with their bags.” | They’re = they are. There = place. Their = ownership. |
Possessives Made Simple
Possessives show ownership and are one of the most searched grammar topics. Use these quick rules:
- Singular nouns: add apostrophe + s. Example: the teacher’s desk.
- Plural nouns ending in s: add only an apostrophe. Example: the teachers’ lounge.
- Plural nouns not ending in s: add apostrophe + s. Example: the children’s books.
- Names ending in s: many American style guides add apostrophe + s. Example: James’s car. Stay consistent in one document.
- Joint ownership: put the possessive on the last name only. Example: Tom and Lisa’s house.
Compound Words: One Word, Two Words or Hyphen?
Compound words confuse many writers because English has no single simple rule. Use these habits:
- Closed compounds are written as one word: notebook, website, everyday (adjective).
- Open compounds are two words: ice cream, high school, every day (adverb phrase).
- Hyphenated compounds often appear before nouns: a well-known author, a part-time job.
- When unsure, check a trusted dictionary and keep your choice consistent through the whole text.
Punctuation Quick Reference
| Mark | Main Use | Example |
|---|---|---|
| Comma | Separates items and clauses | I bought apples, oranges, and pears. |
| Apostrophe | Shows possession or contraction | Maria’s book; don’t |
| Colon | Introduces a list or explanation | You need three things: time, focus, and practice. |
| Semicolon | Joins closely related sentences | I studied hard; the test was easy. |
| Hyphen | Joins words | a long-term plan |
| Quotation marks | Show exact words | She said, “Let’s begin.” |
