Common Writing Mistakes to Avoid (With Examples That Actually Help)
Everyone makes writing mistakes. Even editors. Even people who write for a living. The difference between decent writing and writing that distracts the reader is knowing which mistakes actually matter and how to spot them before you hit send.
Here are ten mistakes worth paying attention to — not the pedantic stuff your tenth-grade English teacher underlined in red, but the ones that genuinely make readers stumble or question your credibility.
1. The Dangling Modifier That Makes No Sense
A dangling modifier is a descriptive phrase that has nothing to attach to in the sentence. The result is confusion — sometimes funny, usually just awkward.
Wrong: Walking into the room, the clock caught my attention.
Why it fails: The clock was not walking into the room. The phrase "walking into the room" has no subject to modify.
Right: Walking into the room, I noticed the clock immediately.
Dangling modifiers are sneaky because your brain fills in the missing subject. You know what you meant. Your reader does not. After every introductory phrase, ask: who or what is doing this? If the next words do not answer that question, rewrite.
2. Run-On Sentences That Never Let the Reader Breathe
Two complete thoughts jammed together without proper punctuation. The reader runs out of mental breath halfway through.
Wrong: The deadline was Friday we submitted on Thursday the client never responded.
Right: The deadline was Friday. We submitted on Thursday. The client never responded.
Sometimes the fix is a period. Sometimes a semicolon or a conjunction. The rule is simple: if both parts could stand as separate sentences, they need more than a comma between them.
3. The Ambiguous Pronoun
A pronoun that could refer to two different things forces the reader to stop and decode. That pause is where you lose people.
Wrong: Sarah told Maria that she was wrong.
Right: Sarah told Maria, "You're wrong." — or — Sarah admitted to Maria that she was wrong.
When "this," "that," "it," "they," or "she" could point in more than one direction, either name the thing explicitly or restructure the sentence. Clarity beats elegance every time.
4. Passive Voice That Hides the Actor
Passive voice is not always wrong. Scientists and lawyers use it deliberately. The problem comes when passive voice hides who did what — usually because you are unsure or trying to dodge responsibility.
Weak: Mistakes were made in the quarterly report.
Stronger: I made mistakes in the quarterly report. — or — The finance team made errors in the quarterly report.
If you know who acted, say so. Reserve passive voice for when the actor genuinely does not matter: "The building was constructed in 1922."
5. The Missing Comma That Changes the Meaning
Commas are not decorative. They control how ideas relate to each other. Leave one out and your sentence says something you did not intend.
Ambiguous: Let's eat Grandma.
Clear: Let's eat, Grandma.
Ambiguous: I enjoy cooking my family and my dog.
Clear: I enjoy cooking, my family, and my dog.
You do not need to memorize every comma rule. Just read your sentence out loud. If you pause naturally, a comma probably belongs there. If the meaning shifts depending on where you pause, the comma is not optional.
6. Wordiness That Buries the Point
Extra words do not make writing sound smarter. They make it harder to follow.
Wordy: Due to the fact that we are experiencing a high volume of requests at this current point in time, there will be a delay in response times.
Clean: We are getting a lot of requests right now, so responses will be slow.
The most common culprits: "due to the fact that" (because), "at this point in time" (now), "in order to" (to), "a number of" (several/many), "in the event that" (if). Kill them all.
7. Inconsistent Verb Tense
Jumping between past and present tense in the same paragraph confuses the reader about when things happened.
Jarring: She walked into the office and sits down at her desk. She opens the report and noticed an error.
Consistent (past): She walked into the office and sat down at her desk. She opened the report and noticed an error.
Consistent (present): She walks into the office and sits down at her desk. She opens the report and notices an error.
Pick a lane and stay in it. Most business and academic writing uses past tense for describing completed actions and present tense for describing current states or general truths.
8. Sentence Fragments That Leave the Reader Hanging
A sentence fragment is an incomplete thought posing as a sentence. Sometimes writers use them for effect. That can work. More often, they are accidents.
Fragment: Because the server crashed during the deployment.
Complete: Because the server crashed during the deployment, we postponed the release.
A quick check: if someone read only that sentence to you out of context, would it make sense? If the answer is no, you have a fragment.
9. Subject-Verb Agreement Errors
Singular subjects need singular verbs. Plural subjects need plural verbs. Simple until the subject gets complicated.
Wrong: The list of features and benefits are impressive.
Right: The list of features and benefits is impressive.
The subject is "list" (singular), not "features and benefits." Prepositional phrases between the subject and verb trick the eye. Strip the sentence down: "The list ... is impressive." Getting this wrong in professional writing signals carelessness more than most other errors.
10. The Weak "There Is" Opening
Starting with "There is" or "There are" buries the interesting part of the sentence behind empty words.
Weak: There are three reasons why the project failed.
Stronger: The project failed for three reasons.
Weak: There is a new policy that addresses remote work.
Stronger: A new policy addresses remote work.
"There is" and "there are" are not grammatically wrong. They are just lazy. Every time you write one, ask if the sentence works without it. Usually it does.
How to Catch These Mistakes Before Anyone Else Does
You do not need to memorize a style guide. Three habits will catch most of these errors:
Read it out loud. Your ear is better at detecting awkward phrasing than your eye. If you stumble while reading, your reader will too.
Let it sit. Even fifteen minutes between writing and editing makes a difference. Fresh eyes see what a tired brain missed.
Read backward. Start with the last sentence and work your way up. This breaks the flow and forces you to see each sentence as a standalone unit — exactly where fragments and agreement errors hide.
