How It Works
Paste your text into the editor. The checker scans for common grammatical patterns, subject-verb agreement errors, and frequently confused words, highlighting issues with suggested corrections.
**Grammar Checker — Write Correctly Every Time**
Grammar errors undermine your credibility whether you're writing an email to a client, a blog post, or an academic paper. ToolVerse's Grammar Checker catches the most common mistakes that spell-checkers miss — agreement errors, wrong word choices, punctuation mistakes, and more.
**What It Checks**
- **Subject-verb agreement** — "He don't know" → "He doesn't know"
- **Apostrophe errors** — "Its" vs "It's", "Your" vs "You're"
- **Homophone confusion** — There/Their/They're, Affect/Effect, Than/Then
- **Double negatives** — "I don't have no time"
- **Comma splices** — Two independent clauses joined only by a comma
- **Run-on sentences** — Sentences that are too long and need breaking up
- **Passive voice** — Flagged (not an error, but often overused)
- **Redundant phrases** — "Past history", "future plans", "end result"
**Common Grammar Mistakes Explained**
*Apostrophes* are one of the most misused punctuation marks. Use an apostrophe to show possession ("John's book") or contraction ("it's" = "it is"). Never use "it's" for possession — the possessive form is "its" (no apostrophe).
*Affect vs. Effect* — "Affect" is usually a verb ("The rain affected the game"). "Effect" is usually a noun ("The effect of the rain was significant"). The mnemonic: RAVEN — Remember Affect Verb, Effect Noun.
*Then vs. Than* — "Then" relates to time ("We ate, then we left"). "Than" is used in comparisons ("She is taller than him").
**When to Use a Grammar Checker**
