How to Fix 10 Common Grammar Gremlins
Ever feel like your writing could be just a little sharper, a touch more professional? You pour your thoughts onto the page, but then those nagging doubts creep in. Did I use the right “there”? Is that comma truly necessary? These aren’t just minor quibbles; they’re common grammar gremlins that can subtly undermine your message, whether you’re crafting an important email, a compelling blog post, or an academic paper. They distract your reader, erode your credibility, and can even change the intended meaning of your words.
The good news? Most of these pesky errors are entirely avoidable with a bit of understanding and practice. This comprehensive guide isn’t about memorizing arcane rules; it’s about empowering you with actionable insights and concrete examples to conquer the ten most prevalent grammar mistakes that plague modern communication. By the end of this journey, you’ll be able to identify, understand, and definitively fix these gremlins, transforming your writing from good to truly exceptional. Let’s banish vagueness and embrace clarity, one perfectly crafted sentence at a time.
1. The Perilous Pronoun-Antecedent Agreement
Few grammatical errors trip up writers as consistently as the failure to ensure a pronoun agrees with its antecedent – the noun or noun phrase it replaces – in number (singular/plural) and gender (masculine/feminine/neuter). When these don’t align, sentences become clunky, confusing, and grammatically unsound.
The Gremlin: Using a singular pronoun to refer to a plural antecedent, or vice-versa, or using a gender-specific pronoun for a gender-neutral antecedent. This often surfaces with indefinite pronouns or collective nouns.
The Fix: Always make sure your pronoun is a perfect match for the noun it stands in for.
Common Culprits & Solutions:
- Indefinite Pronouns (e.g., everyone, someone, nobody, each, either, neither): These are inherently singular, even if they feel plural.
- Incorrect: Everyone in the class needs to bring their own lunch.
- Why it’s wrong: “Everyone” is singular, but “their” is plural.
- Corrected (Option 1 – Rephrasing for clarity): Everyone in the class needs to bring his or her own lunch. (While grammatically correct, this can sound clunky.)
- Corrected (Option 2 – Pluralizing the noun): All students in the class need to bring their own lunch. (Simplest and often best.)
- Corrected (Option 3 – Rephrasing the sentence without a pronoun): Everyone in the class needs to bring an individual lunch.
- Example 2: Neither of the sisters wanted to share their toy.
- Why it’s wrong: “Neither” is singular, “their” is plural.
- Corrected: Neither of the sisters wanted to share her toy.
- Example 3: Someone left their umbrella in the lobby.
- Why it’s wrong: “Someone” is singular, “their” is plural.
- Corrected: Someone left his or her umbrella in the lobby. (Or, if context allows, “Someone left an umbrella in the lobby.”)
- Collective Nouns (e.g., team, committee, audience, family, group): These can be singular or plural depending on whether the members are acting as a single unit or as individuals.
- When acting as a unit (singular):
- Incorrect: The team celebrated their victory with a pizza party.
- Why it’s wrong: The team is acting as one unit here.
- Corrected: The team celebrated its victory with a pizza party.
- When acting as individuals (plural):
- Example: The team argued among themselves about the strategy.
- Why it’s right: The individual members of the team are arguing, not the team as a singular entity.
- Correct: The team argued among themselves about the strategy. (Here, “themselves” is correct because the team members are acting individually.)
- When acting as a unit (singular):
- Gender Neutrality and “They/Their”: While “they/their” is gaining acceptance as a singular, gender-neutral pronoun, especially in informal contexts, in formal writing, it’s often still best to rephrase or use “he or she” if the gender is truly unknown and you want to maintain strict grammatical formality. However, use of singular “they” is increasingly becoming acceptable and common to avoid awkward phrasing. The key is consistency and clarity within your chosen style guide.
- Example (Ambiguous gender): A student must submit their essay by Friday.
- Current Acceptable (and often preferred) usage: A student must submit their essay by Friday. (Used when the gender of the specific student is unknown or irrelevant.)
- Formal/Traditional alternative: A student must submit his or her essay by Friday.
- Best rephrasing: Students must submit their essays by Friday. (Pluralizing the noun often elegantly resolves the issue.)
2. The Mighty Modifier Misplacement
Misplaced modifiers are like grammatical booby traps, lurking to ambush your reader with unintended hilarity or, worse, profound confusion. A modifier is a word, phrase, or clause that describes or adds information to another word in the sentence. When it’s not placed next to the word it’s supposed to modify, mayhem ensues.
The Gremlin: A descriptive word or phrase that appears to modify the wrong noun or verb because of its awkward placement in the sentence.
The Fix: Place your modifiers as close as possible to the words they describe.
Concrete Examples & Solutions:
- Misplaced Adverb (e.g., only, almost, nearly, just): The placement of these small words can drastically alter meaning.
- Incorrect: She only eats vegetables. (Implies she doesn’t do anything else besides eating vegetables.)
- Why it’s wrong: “Only” is modifying “eats,” implying eating is the only thing she does.
- Corrected: She eats only vegetables. (Meaning vegetables are the only food she eats.)
- Example 2: He almost lost $50. (Implies he didn’t lose any money at all, but came close.)
- Corrected: He lost almost $50. (Meaning he lost a significant amount, close to $50.)
- Misplaced Phrases:
- Incorrect: He bought a dog for his sister with long ears.
- Why it’s wrong: This sentence ambiguously suggests the sister has long ears, not the dog.
- Corrected: He bought a dog with long ears for his sister.
- Example 2: Walking through the park, a squirrel startled me.
- Why it’s wrong: Grammatically, this suggests the squirrel was walking through the park. This is a common “dangling modifier” (see below).
- Corrected: As I was walking through the park, a squirrel startled me.
- Corrected (passive voice): While walking through the park, I was startled by a squirrel.
- Misplaced Clauses:
- Incorrect: I saw a car go by with a broken headlight traveling at high speed.
- Why it’s wrong: “Traveling at high speed” appears to modify “headlight” or “go by” in an unclear way.
- Corrected: I saw a car with a broken headlight that was traveling at high speed. (Or, more concisely: “I saw a high-speed car with a broken headlight.”)
3. The Dreaded Dangling Modifier
Often confused with misplaced modifiers, a dangling modifier is a specific type of modifier error where the word or phrase being modified is missing from the sentence entirely, leaving the modifier “dangling” without a clear subject.
The Gremlin: A descriptive phrase that doesn’t logically modify anything in the sentence, typically because the implied subject of the phrase isn’t the actual subject of the main clause.
The Fix: Either add the subject that the modifier refers to, or rephrase the sentence entirely to clarify the intended meaning.
Concrete Examples & Solutions:
- Introductory Participial Phrases: These are prime candidates for dangling.
- Incorrect: Having finished the report, the coffee machine beckoned.
- Why it’s wrong: Grammatically, this implies the coffee machine finished the report.
- Corrected: Having finished the report, I was beckoned by the coffee machine. (Adding the true subject “I”).
- Corrected (Rephrased): After I finished the report, the coffee machine beckoned.
- Introductory Gerund Phrases:
- Incorrect: To get good grades, studying diligently is necessary.
- Why it’s wrong: “Studying diligently” doesn’t “get good grades” in the same way a person does.
- Corrected: To get good grades, you must study diligently. (Adding the implied subject “you”).
- Corrected (Rephrased): Studying diligently is necessary to get good grades.
- Implied Subject:
- Incorrect: Covered in mud, I decided the dog needed a bath.
- Why it’s wrong: This suggests you were covered in mud, not the dog.
- Corrected: Covered in mud, the dog needed a bath, so I decided to give it one.
- Corrected (Rephrased): I decided the dog, covered in mud, needed a bath.
The key to fixing dangling modifiers is to ask yourself, “Who or what is performing the action or being described by this introductory phrase?” Then, ensure that noun or pronoun immediately follows the phrase or is clearly introduced in the main clause.
4. The Comma Catastrophe: Overuse, Underuse, and Misuse
Commas are vital punctuation marks, acting as traffic signals in your sentences. They clarify meaning, separate ideas, and improve readability. However, their misuse – either in excess or by omission – can lead to confusion and disrupt the flow of your writing.
The Gremlin: Commas placed where they don’t belong, omitted where they’re crucial, or misapplied in common constructions.
The Fix: Understand the core functions of commas and apply them consistently. When in doubt, err on the side of clarity.
Key Scenarios & Solutions:
- Joining Independent Clauses with a Conjunction (FANBOYS: for, and, nor, but, or, yet, so): This is one of the most common applications. When two complete thoughts (independent clauses) are joined by one of these conjunctions, a comma is required before the conjunction.
- Incorrect: The sun set and the stars appeared.
- Why it’s wrong: Two independent clauses joined without a comma. This is a run-on sentence.
- Corrected: The sun set, and the stars appeared.
- Incorrect: She wanted to go to the concert but she couldn’t find her ticket.
- Corrected: She wanted to go to the concert, but she couldn’t find her ticket.
- After Introductory Elements: Phrases or clauses that come before the main independent clause generally require a comma. This helps signal to the reader that the main subject and verb are about to appear.
- Incorrect: After a long day at work I just wanted to relax.
- Corrected: After a long day at work, I just wanted to relax.
- Incorrect: If you are ready we can leave now.
- Corrected: If you are ready, we can leave now.
- Note: Very short introductory phrases (e.g., “Yesterday I left.”) often omit the comma without loss of clarity, but including it is never wrong.
- Separating Items in a Series (Oxford Comma/Serial Comma): This is a point of stylistic debate, but for maximum clarity, always use a comma before the last item in a list, even if it’s preceded by “and” or “or.”
- Ambiguous: I bought apples oranges and bananas. (Could imply oranges-and-bananas is a single item.)
- Clear: I bought apples, oranges, and bananas.
- Example (potentially confusing without Oxford comma): My favorite sandwiches are ham and cheese, peanut butter and jelly and tuna. (Without the comma before the final “and,” it looks like “jelly and tuna” is one item.)
- Clear: My favorite sandwiches are ham and cheese, peanut butter and jelly, and tuna.
- Setting Off Non-Essential Information (Non-Restrictive Clauses/Phrases): Information that adds detail but isn’t strictly necessary for the meaning of the sentence should be set off with commas (like parentheses). If you remove the information, the sentence still makes sense.
- Incorrect: My brother who lives in Vancouver visited last week. (This implies you have multiple brothers, and you’re specifying which one.)
- Corrected: My brother, who lives in Vancouver, visited last week. (This implies you have only one brother, and his living in Vancouver is additional, non-essential info.)
- Corrected (Restrictive – No commas): The student who scored highest received a scholarship. (Here, “who scored highest” is essential to identify which student, so no commas are used.)
- Example 2: The meeting on Tuesday which was very productive lasted three hours.
- Corrected: The meeting on Tuesday, which was very productive, lasted three hours.
- Separating Adjectives: Use a comma between two or more adjectives that modify the same noun, if you could swap their order or place “and” between them.
- Incorrect: He drives a big old car.
- Corrected: He drives a big, old car.
- Incorrect: It was a dark stormy night.
- Corrected: It was a dark, stormy night.
- Note: Do not use a comma if the adjectives are cumulative and are not independent (e.g., “a bright red apple” – you wouldn’t say “red bright apple” or “bright and red apple”).
5. The Apostrophe Aberration: Possession vs. Contraction vs. Plural
The apostrophe has only a few jobs, but people routinely confuse them, leading to some of the most visible and frustrating errors in English writing.
The Gremlin: Misusing apostrophes for plurals (the “greengrocer’s apostrophe”), confusing possessives with contractions, or incorrectly forming possessives, especially with “its” and “it’s.”
The Fix: Master the three primary uses of the apostrophe.
The Three Rules & Solutions:
- 1. To Show Possession:
- Singular Noun: Add ‘s.
- Correct: The dog’s collar (The collar belongs to one dog).
- Correct: Chris’s car (Even ending in ‘s’, most style guides prefer ‘s for singular nouns).
- Plural Noun Ending in ‘s’: Add only an apostrophe after the ‘s’.
- Correct: The students’ essays (The essays belong to multiple students).
- Correct: The boys’ club (A club for multiple boys).
- Irregular Plural Noun (not ending in ‘s’): Add ‘s.
- Correct: The children’s toys (Toys belonging to multiple children).
- Correct: The men’s locker room (A locker room for multiple men).
- Singular Noun: Add ‘s.
- 2. To Form Contractions (Shortened Forms of Words): The apostrophe replaces the missing letters.
- Incorrect: Theyre going to the party.
- Corrected: They’re going to the party. (They’re = They + are)
- Incorrect: Dont forget your keys.
- Corrected: Don’t forget your keys. (Don’t = Do + not)
- Crucial Distinction: Its vs. It’s
- It’s: A contraction of “it is” or “it has.”
- Incorrect: The dog wagged its tail. (Incorrectly implies “it is tail”)
- Corrected: The dog wagged its tail. (Possessive, no apostrophe needed)
- Correct: It’s a beautiful day. (It is a beautiful day.)
- Correct: It’s been a long time. (It has been a long time.)
- Its: A possessive pronoun meaning “belonging to it.” Unlike other possessive pronouns (hers, yours, ours, theirs), “its” does not get an apostrophe.
- Correct: The cat licked its paws.
- Correct: The company is known for its innovative products.
- It’s: A contraction of “it is” or “it has.”
- 3. To Form Plurals of Single Letters, Numbers, or Symbols (Rarely, for Clarity): Most style guides prefer simply adding ‘s’ without an apostrophe for plurals of numbers or years (e.g., 1990s). However, for single letters, an apostrophe can prevent confusion.
- Correct (Clarity): Mind your p’s and q’s.
- Less common but seen: The 1920’s (Many prefer 1920s without apostrophe).
Never use an apostrophe to form a simple plural noun!
- Incorrect: Apple’s for sale.
- Incorrect: DVD’s are outdated.
- Corrected: Apples for sale.
- Corrected: DVDs are outdated.
6. Semicolon Scramble: When to Use Them, When to Skip Them
The semicolon; a mysterious punctation mark that often feels intimidating. Yet, when used correctly, it adds sophistication and precision to your writing, showing a relationship between ideas that is stronger than a comma but less separate than a period.
The Gremlin: Using semicolons interchangeably with commas or periods, or simply avoiding them due to uncertainty.
The Fix: Understand the specific functions of semicolons and apply them purposefully.
Key Uses & Solutions:
- 1. To Join Two Closely Related Independent Clauses (Without a Coordinating Conjunction): When two complete thoughts are so interdependent that a period would create too much of a break, but a comma wouldn’t be strong enough (and there’s no FANBOYS conjunction), a semicolon is your friend.
- Incorrect (Run-on): She loves to read she finishes a book every day.
- Corrected (Comma Splice): She loves to read, she finishes a book every day. (Still a comma splice unless a conjunction is added)
- Corrected (Semicolon): She loves to read; she finishes a book every day. (Shows a direct cause-and-effect or very close relationship)
- Example 2: The deadline is approaching; we must work quickly.
- 2. To Join Independent Clauses When the Second Clause Begins with a Conjunctive Adverb (e.g., however, therefore, moreover, consequently, in fact, on the other hand): When you use these words to connect two independent clauses, a semicolon precedes the conjunctive adverb, and a comma follows it.
- Incorrect: I wanted to go however I was too tired.
- Corrected: I wanted to go; however, I was too tired.
- Example 2: It rained all week; consequently, the picnic was cancelled.
- 3. To Separate Items in a Complex List (Where Items Already Contain Commas): This prevents confusion when listed items themselves contain internal commas.
- Confusing: We visited London, England, Paris, France, and Rome, Italy.
- Clear: We visited London, England; Paris, France; and Rome, Italy.
- Example 2: The conference attendees included Dr. Smith, a renowned biologist; Professor Jones, a historian; and Ms. Chen, a data scientist.
When NOT to Use Semicolons:
* Never use a semicolon to separate an independent clause from a dependent clause. (Use a comma).
* Never use a semicolon to introduce a list. (Use a colon).
* Never use a semicolon with a coordinating conjunction (FANBOYS) to join two independent clauses. (Use a comma).
7. The Hyphen Havoc: Compound Modifiers and Clarity
Hyphens are small but powerful little marks that join words together to create compound meanings, typically to avoid ambiguity. Their absence or misuse can completely change the intended meaning.
The Gremlin: Failing to use hyphens in compound modifiers, or using them unnecessarily.
The Fix: Use hyphens to combine two or more words into a single concept when that concept functions as a modifier before a noun.
Key Rule & Solutions:
- Rule: Use a hyphen to connect two or more words that function together as a single adjective immediately preceding a noun.
- Incorrect: She adopted a well behaved dog. (Could mean the dog was “well” and also “behaved” separately.)
- Corrected: She adopted a well-behaved dog. (The dog is “behaved” in a “well” manner.)
- Incorrect: He ordered a first class ticket. (Could mean a “first” ticket that is “class.”)
- Corrected: He ordered a first-class ticket. (The ticket is “of the first class.”)
- Incorrect: This is a much needed discussion.
- Corrected: This is a much-needed discussion.
- Incorrect: We planned a two week vacation.
- Corrected: We planned a two-week vacation.
When NOT to Use Hyphens:
- When the compound modifier comes after the noun: The hyphen is usually dropped because the words are no longer functioning as a single adjective modifying the noun.
- Correct: The dog was well behaved. (No hyphen after the noun.)
- Correct: The ticket was first class.
- Correct: The discussion was much needed.
- Correct: The vacation was two weeks long.
- When the first word in a two-word modifier is an adverb ending in -ly: Adverbs ending in -ly automatically modify the following adjective, so a hyphen is unnecessary and should be omitted.
- Incorrect: This is a highly-regarded book.
- Corrected: This is a highly regarded book.
- Incorrect: She gave a clearly-stated answer.
- Corrected: She gave a clearly stated answer.
- With common prefixes: Most prefixes (like un-, re-, pre-, anti-) don’t require hyphens unless they precede a proper noun or vowel that would cause confusion.
- Correct: unhelpful, reread, predetermine, antivirus, cooperate, coordinate.
- Requires hyphen: pre-Columbian, anti-inflammatory, re-enter.
8. Effect vs. Affect: The Dynamic Duo of Confusion
This pair is a classic, frustrating even seasoned writers. They sound similar, but their grammatical roles and meanings are distinct.
The Gremlin: Using “affect” when “effect” is needed, or vice-versa.
The Fix: Remember that “affect” is usually a verb, and “effect” is usually a noun.
The Rule & Solutions:
- Affect (Verb): To influence, to produce a change in.
- Incorrect: The weather had a bad effect on my mood. (Should be “affect” for the action.)
- Corrected: The weather had a bad effect on my mood. (“Effect” as noun, correct)
- Correct usage with Affect: The weather affected my mood. (Verb – it influenced my mood.)
- Correct usage with Affect: His opinion doesn’t affect my decision. (Verb – it doesn’t influence my decision.)
- Correct usage with Affect: The disease affects the respiratory system. (Verb – it impacts the system.)
- Effect (Noun): The result, consequence, or outcome of an action or influence.
- Incorrect: The drug quickly effected a cure. (Should be “effected” if it’s the result, but often “effected” used as a verb is more about bringing about change.)
- Corrected: The drug quickly effected a cure. (Less commonly, “effect” can be a verb meaning “to bring about” or “to accomplish,” but this is a specific, formal use.)
- Correct usage with Effect: The new policy will have a positive effect on morale. (Noun – it will have a positive outcome.)
- Correct usage with Effect: What was the effect of his speech? (Noun – what was the result?)
- Correct usage with Effect: The special effects in the movie were amazing. (Noun – the results of technical wizardry.)
The “Effect” as a Verb Exception:
While rare in everyday use, “effect” can be a verb meaning “to bring about” or “to accomplish.”
* Example: The manager hoped to effect a change in employee behavior. (Meaning: to bring about a change.)
* This is distinct from “affect” (to influence). “Affect” is about influencing an existing state; “effect” (as a verb) is about creating a new state or bringing something into being.
Mnemonic:
* A is for Action (Affect = Verb)
* E is for End result (Effect = Noun)
9. Less vs. Fewer: Counting vs. Quantity
This distinction is straightforward, yet it consistently trips up writers. It’s all about whether what you’re describing can be counted individually.
The Gremlin: Using “less” with countable nouns or “fewer” with uncountable nouns.
The Fix: If you can count the individual items, use “fewer.” If you’re talking about an undifferentiated quantity or amount, use “less.”
The Rule & Solutions:
- Fewer (for Countable Nouns): Use “fewer” when referring to individual items that can be counted discretely.
- Correct: I have fewer apples than you. (You can count individual apples.)
- Correct: There are fewer cars on the road today. (You can count individual cars.)
- Correct: We need fewer meetings and more action. (You can count individual meetings.)
- Common Error: The express lane is for 10 items or less.
- Correction: The express lane is for 10 items or fewer.
- Less (for Uncountable Nouns/Amounts/Abstract Concepts): Use “less” when referring to a quantity that cannot be counted individually, or when referring to an amount or degree.
- Correct: I have less money than you. (You don’t count “moneys,” but an amount of money.)
- Correct: There is less traffic today. (Traffic is a collective, uncountable amount.)
- Correct: She feels less stress after her vacation. (Stress is an abstract, uncountable concept.)
- Correct: Pour less water into the glass. (Water is an uncountable fluid.)
10. Who vs. Whom: The Case of the Right Pronoun
“Who” and “whom” are often intimidating, leading writers to guess or avoid them. However, the rule is surprisingly simple once you understand it, relying on the concept of subject and object.
The Gremlin: Incorrectly using “who” (subjective case) when “whom” (objective case) is required, or vice-versa.
The Fix: Substitute “he/she” for “who” and “him/her” for “whom” to determine the correct case.
The Rule & Solutions:
- “Who” (Subjective Case): Use “who” when the pronoun is the subject of a verb or when it’s functioning as a predicate nominative (following a linking verb). It performs the action.
- Think: “He” or “She”
- Correct: Who ate the last slice of pizza? (He ate it.)
- Correct: I wonder who will win the election. (He will win.)
- Correct: Sarah is the one who organized the event. (She organized it.)
- “Whom” (Objective Case): Use “whom” when the pronoun is the object of a verb or a preposition. It receives the action or is affected by the preposition.
- Think: “Him” or “Her”
- Incorrect: Who are you talking to? (This is a very common informal usage, but technically incorrect in formal writing.)
- Corrected: To whom are you talking? (You are talking to him.)
- Corrected (rephrased for natural flow): Whom did you invite? (You invited him.)
- Correct: Whom did the committee select? (The committee selected him/her.)
- Correct: Give the package to whom you see first. (You see him first.)
The He/Him Trick: This is the most reliable way to conquer “who” vs. “whom.”
1. Isolate the clause containing “who/whom.”
2. Replace “who/whom” with “he/him” (or “she/her”).
3. If “he” or “she” sounds correct, use “who.”
4. If “him” or “her” sounds correct, use “whom.”
Example: Sarah is the one (who/whom) organized the event.
* Test: (She/Her) organized the event. “She organized the event” sounds correct. Therefore, “Sarah is the one who organized the event.”
Example: To (who/whom) should I address the letter?
* Test: Should I address the letter to (he/him)? “Should I address the letter to him” sounds correct. Therefore, “To whom should I address the letter?”
