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

Q: How accurate are automated grammar checkers?

Modern grammar checkers are highly accurate for common errors but may struggle with context-dependent issues, creative writing, or specialized terminology. They're best used as writing assistants rather than replacements for human judgment. Always review suggestions critically and consider your specific context and audience.

Q: Should I accept all grammar checker suggestions?

No, not all suggestions should be accepted blindly. Grammar checkers may not understand your intended meaning, stylistic choices, or specific context. Use suggestions as starting points for improvement, but maintain your voice and intent. Consider whether each suggestion truly improves clarity and correctness.

Q: Can grammar checkers help improve my writing skills?

Yes, when used thoughtfully. Pay attention to explanations provided with suggestions to understand underlying grammar rules. Track common errors in your writing and focus on improvement areas. However, combine automated checking with studying grammar rules, reading quality writing, and seeking feedback from skilled writers.

Q: How do I handle conflicting grammar rules?

Grammar rules can vary by style guide, region, and context. When facing conflicts, consider your audience, purpose, and any specific style requirements (APA, MLA, Chicago, etc.). Some “rules” are actually stylistic preferences. Choose the option that best serves your communication goals and maintain consistency throughout your document.

Q: What's the difference between grammar and style checking?

Grammar checking focuses on correctness according to established rules (subject-verb agreement, punctuation, etc.), while style checking addresses clarity, conciseness, tone, and readability. Both are important for effective writing, but style suggestions are more subjective and depend on context, audience, and purpose.

Q: How can I improve my grammar without relying on checkers?

Read extensively in your target genre, study grammar systematically, practice writing regularly, and seek feedback from experienced writers or editors. Keep a personal error log to track improvement areas, and gradually develop intuitive grammar sense through exposure and practice. Use checkers as learning tools, not crutches.

Q: Are there different standards for different types of writing?

Yes, grammar and style expectations vary significantly across contexts. Academic writing requires formal tone and complex structures, business writing emphasizes clarity and professionalism, creative writing allows more flexibility, and casual communication permits informal constructions. Adjust your approach based on audience and purpose.
