Grammar Rules and Common Errors

Subject-Verb Agreement

One of the most fundamental grammar rules requiring the subject and verb to agree in number. Singular subjects take singular verbs, while plural subjects take plural verbs.

Common Errors:

❌ The group of students are ready.
✅ The group of students is ready.
❌ Each of the books have problems.
✅ Each of the books has problems.

Key Rule: The verb agrees with the subject, not with words that come between the subject and verb.

Pronoun-Antecedent Agreement

Pronouns must agree with their antecedents in number, gender, and person. This rule ensures clarity and prevents confusion about who or what the pronoun refers to.

Common Errors:

❌ Everyone should bring their lunch.
✅ Everyone should bring his or her lunch.
❌ The company changed their policy.
✅ The company changed its policy.

Key Rule: Singular antecedents require singular pronouns; collective nouns are usually singular.

Verb Tense Consistency

Maintaining consistent verb tenses throughout a piece of writing helps readers follow the timeline of events and understand the relationship between different actions.

Common Errors:

❌ She walked to the store and buys groceries.
✅ She walked to the store and bought groceries.
❌ I was reading when the phone rings.
✅ I was reading when the phone rang.

Key Rule: Keep tenses consistent within sentences and paragraphs unless time changes.

Misplaced and Dangling Modifiers

Modifiers should be placed as close as possible to the words they modify. Misplaced or dangling modifiers can create confusion or unintended humor.

Common Errors:

❌ Running quickly, the finish line appeared ahead.
✅ Running quickly, I saw the finish line ahead.
❌ She served cake to the children on paper plates.
✅ She served cake on paper plates to the children.

Key Rule: Ensure modifiers have a clear, logical word to modify and place them appropriately.

Comma Usage and Punctuation

Proper comma usage clarifies meaning and improves readability. Understanding when to use commas prevents run-on sentences and comma splices while ensuring clarity.

Common Errors:

❌ I went to the store I bought milk. (Comma splice)
✅ I went to the store, and I bought milk.
❌ My friend who lives nearby visits often.
✅ My friend, who lives nearby, visits often.

Key Rule: Use commas to separate independent clauses, set off non-essential information, and clarify meaning.

Frequently Asked Questions

How accurate is the grammar checker?

Our grammar checker uses advanced natural language processing to provide highly accurate suggestions. However, language is complex and context-dependent, so it's always a good idea to use your own judgment and review suggestions carefully.

Does the tool store my data?

No, we prioritize your privacy. All grammar checking is performed client-side in your browser, and your text is never stored on our servers. Your data remains secure and confidential.

Can it check for plagiarism?

Currently, our tool focuses exclusively on grammar, spelling, punctuation, and style. We do not offer plagiarism checking, but we may consider adding this feature in the future.

Does it work with different English dialects?

The grammar checker is designed to handle common variations between American, British, and other English dialects. It recognizes differences in spelling (e.g., color/colour) and vocabulary, providing suggestions appropriate for your chosen dialect.

Is there a limit to the text length?

There is no strict limit, but performance may vary with extremely long documents. For best results, we recommend checking text in manageable sections, such as a chapter or article at a time, to ensure smooth performance and focused review.
