10 Grammar Rules Every Writer Should Know
Published January 2026 | Written by Faizan the Coder
Grammar is the foundation of all good writing. You might have amazing ideas, but without the right structure, your message can get lost or misunderstood. These 10 timeless grammar rules will help you write clearly, confidently, and professionally — whether you’re crafting an essay, blog post, or business email.
1. Use Active Voice Whenever Possible
Active voice makes your writing stronger and more engaging. Instead of saying, “The ball was thrown by Ali,” write “Ali threw the ball.” Active sentences are shorter, clearer, and more direct.
Tip: Passive voice isn’t always wrong, but overusing it can make your writing sound distant or weak.
2. Maintain Consistent Verb Tenses
Shifting between past, present, and future tenses confuses readers. Stick to one main tense per section.
✅ “I walked into the room and turned on the light.”
❌ “I walked into the room and turn on the light.”
3. Ensure Subject-Verb Agreement
Singular subjects need singular verbs, and plural subjects need plural verbs.
✅ “She runs fast.”
❌ “She run fast.”
It sounds simple, but this mistake appears often in long, complex sentences.
4. Avoid Run-On Sentences
Two independent thoughts shouldn’t run together without punctuation or conjunctions.
❌ “I love writing it helps me relax.”
✅ “I love writing because it helps me relax.”
Use commas, periods, or semicolons to separate ideas.
5. Master Comma Usage
Commas clarify meaning. Use them after introductory phrases, between items in a list, and before coordinating conjunctions in compound sentences.
Example: “After lunch, we discussed the project.”
But don’t overdo it — too many commas can break your flow.
6. Avoid Misplaced Modifiers
Modifiers describe something — so they must be placed next to the word they modify.
❌ “Running quickly, the finish line was crossed by Sara.”
✅ “Running quickly, Sara crossed the finish line.”
This small change makes your sentence grammatically correct and logical.
7. Learn Commonly Confused Words
Even experienced writers mix up similar-sounding words. Here are a few to watch out for:
- There / Their / They’re — location / possession / contraction.
- Your / You’re — possession / “you are.”
- Affect / Effect — verb (to influence) / noun (result).
- Its / It’s — possession / “it is.”
8. Keep Parallel Structure
When listing ideas, use a consistent grammatical pattern.
❌ “I love to read, writing, and to paint.”
✅ “I love reading, writing, and painting.”
This improves flow and rhythm — especially in essays or speeches.
9. Avoid Double Negatives
Two negatives cancel each other out and make sentences confusing.
❌ “I don’t need no help.”
✅ “I don’t need any help.”
Keep your statements clear and positive.
10. Always Proofread Before Publishing
Even great writers make mistakes. Proofreading ensures accuracy and polish. Read your work aloud — it helps catch awkward phrasing or missing words.

Bonus Tip: Simplicity Wins
Fancy words don’t make writing better — clarity does. If your readers understand you instantly, you’ve succeeded. Great grammar serves your ideas, not the other way around.
Final Thoughts
Grammar isn’t about strict rules — it’s about making your writing effortless to read and professional in tone. The more you write and revise, the more naturally these rules will come to you. Keep learning, practice regularly, and use tools like CountIt4U to help your words shine.
