Common English Grammar Mistakes and Fixes

The Perils of Apostrophes: Possession and Contraction Catastrophes

Ah, the humble apostrophe. It’s a small mark, easily overlooked, yet it wields considerable power over clarity and correctness in English. You’ve seen them, haven’t you? The misplaced apostrophes that turn a perfectly sensible sentence into a grammatical quagmire. It’s a common pitfall, and one that can easily be navigated with a little understanding.

Possessive Pronouns vs. Possessive Nouns: The “Its” and “Yours” Conundrum

This is where most people stumble. You’re trying to indicate that something belongs to someone or something, and suddenly the apostrophe seems to appear and disappear like a mischievous sprite. Let’s break down the key culprits: “its” versus “it’s.”

The Mistake: You’ll often see “it’s” used to show possession when it should be “its.” For example, “The dog wagged it’s tail.” This sounds right, doesn’t it? Your ear might be telling you it’s a possessive, and it is, but the spelling is wrong. The same confusion can extend to other possessive pronouns like “yours,” “hers,” “his,” “ours,” and “theirs.”
The Fix: This is the golden rule: **Possessive pronouns (its, yours, hers, his, ours, theirs) never, ever use an apostrophe.**
Correct: “The dog wagged its tail.” (The tail belongs to the dog.)
Correct: “Yours is the blue car.” (The car belongs to you.)
Correct: “The book is hers.” (The book belongs to her.)
When IS an Apostrophe Needed? Apostrophes are used for possessive nouns and contractions.
Possessive Nouns: To show possession with a noun, you generally add an apostrophe and an “s.”
Correct: “The dog’s bone.” (The bone belongs to the dog.)
Correct: “The students’ essays.” (The essays belong to the students. Note: for plural nouns ending in ‘s’, you add the apostrophe after the ‘s’.)
Correct: “Sarah’s car has a flat tire.” (The car belongs to Sarah.)
Contractions: When you’re combining two words and omitting letters, the apostrophe shows where the missing letters would have been.
Correct: “It’s a beautiful day.” (This is a contraction of “it is.”)
Correct: “You’re going to love this listicle.” (This is a contraction of “you are.”)
Correct: “They’re heading to the park.” (This is a contraction of “they are.”)

Think of it this way: If you can replace the word with “it is” or “it has,” then “it’s” (with the apostrophe) is correct. If you’re indicating belonging, and you cannot replace it with “it is” or “it has” without changing the meaning, then use “its” (without the apostrophe).

The Apostrophe in Plurals: A Common Misconception

This is another area where your good intentions can lead you astray. You want to pluralize a word, and the apostrophe seems like a helpful addition. But here’s the reality: apostrophes are rarely, if ever, used to make a word plural.

The Mistake: You’ll often see something like: “Fresh apple’s for sale,” or “We saw three Katy Perry’s in concert.” This is a classic error, driven by a desire to make things look more formal or distinct.
The Fix: For most plurals, you simply add an “-s” or “-es.”
Correct: “Fresh apples for sale.”
Correct: “We saw three Katy Perrys in concert.” (While names can sometimes feel like exceptions, in this context, it’s the plural form of the name representing multiple instances or people).
Correct: “My brothers’ birthdays are in July.” (Here, the apostrophe is correct because it’s showing possession, plural brothers, meaning birthdays belonging to multiple brothers.)

There are a few very rare exceptions for clarity, such as when pluralizing single letters (e.g., “mind your p’s and q’s”) or when pluralizing numbers when they are being used as nouns themselves (e.g., “Sales of the 1990s were strong,” though even this is sometimes debated and “sales of the 1990s” is generally accepted). However, for everyday writing, stick to the rule: no apostrophes for simple plurals.

Verb Agreement Antics: Singular vs. Plural Predicaments

Verbs, the action words of our sentences, need to agree with their subjects in number. This means a singular subject takes a singular verb, and a plural subject takes a plural verb. While this sounds straightforward, the complexities of sentence structure can make it surprisingly tricky. You might be surprised how often this subtle mismatch creeps into writing.

The Subject-Verb Agreement Basics: Standard Rules and Exceptions

At its core, subject-verb agreement is about ensuring your verb form matches the number of your subject.

The Mistake: You’ll often see sentences like: “The team are playing well.” Or, “My friends is coming over tonight.” This is where the confusion between what seems logical and what is grammatically correct can cause problems. We often think of “team” as referring to multiple people, so we want to use a plural verb.
The Fix: Remember to identify the grammatical subject of the sentence and match the verb accordingly.
Correct: “The team is playing well.” (Here, “team” is treated as a single unit, a singular noun.)
Correct: “My friends are coming over tonight.” (“Friends” is explicitly plural.)
Collective Nouns: This is a big one. Collective nouns (words that refer to a group of people or things) can be tricky.
When treated as a unit: If the group is acting as a single entity, use a singular verb. Examples include: team, committee, family, government, jury, audience, class.
Correct: “The committee has decided on the new policy.”
Correct: “My family is going on vacation.”
When emphasizing individual members: If the sentence focuses on the individuals within the group, you might use a plural verb. This is less common and depends heavily on context and regional variation (e.g., American English tends to favor singular for collective nouns more strongly than British English).
Less common but potentially correct: “The jury are filing out of the courtroom one by one.” (Emphasizes the individual actions.)

The Impact of Intervening Phrases and Clauses

One of the most common reasons for subject-verb agreement errors is the presence of phrases or clauses that come between the subject and the verb. These add extra words, often causing you to lose sight of the core subject.

The Mistake: Consider a sentence like: “The package, along with the letters and the photographs, are damaged.” Your eye might be drawn to “letters” and “photographs,” which are plural, leading you to choose the plural verb “are.”
The Fix: When you encounter these intervening phrases, mentally (or even physically!) remove them to isolate the true subject and verb. Phrases starting with “along with,” “as well as,” “in addition to,” “together with,” and “accompanied by” do not make the subject plural.
Correct: “The package (along with the letters and the photographs) is damaged.” (The subject is the singular noun “package.”)
Correct: “The report, which has been thoroughly reviewed by the board, shows a significant increase in profits.” (The subject is the singular noun “report.”)

This exploration of language intricacies can enhance your overall grasp of grammar and vocabulary. You can read more about it in this insightful piece on the difference between wissen and kennen in German.

“Either/Or” and “Neither/Nor” Conundrums

These pairs of conjunctions introduce another layer of complexity to subject-verb agreement. The rule here is quite specific and often overlooked.

The Mistake: You might write: “Either John or his sisters is going to the party.” Or, “Neither the manager nor the employees was aware of the change.” The confusion arises from deciding whether to consider the subjects individually or collectively.
The Fix: When using “either…or” or “neither…nor,” the verb should agree with the subject that is closest to it.
Correct: “Either John or his sisters are going to the party.” (The closest subject is “sisters,” which is plural.)
Correct: “Either his sisters or John is going to the party.” (The closest subject is “John,” which is singular.)
Correct: “Neither the manager nor the employees were aware of the change.” (The closest subject is “employees,” which is plural.)
Correct: “Neither the employees nor the manager was aware of the change.” (The closest subject is “manager,” which is singular.)

This rule can feel a bit counterintuitive sometimes, so it’s worth practicing.

Pronoun Pitfalls: Agreement and Reference Revelations

Pronouns are the workhorses of your sentences, replacing nouns to avoid repetition. But when a pronoun doesn’t agree with its antecedent (the noun it refers to), or when its reference is unclear, your writing can become confusing and even misleading. You want your readers to know exactly who or what you’re talking about.

Pronoun-Antecedent Agreement: The Number Game

Just like subjects and verbs, pronouns must agree in number with the nouns they replace.

The Mistake: You’ll see sentences like: “Each student must bring their own lunch.” Or, “Every employee should submit their report by Friday.” The common tendency here is to use the plural pronoun “their” to refer back to a singular antecedent like “each student” or “every employee,” often for reasons of inclusivity or to avoid awkward phrasing.
The Fix: The most grammatically traditional approach is to ensure number agreement.
Correct (traditional): “Each student must bring his or her own lunch.” (Awkward, but grammatically sound).
Correct (traditional): “Every employee should submit his or her report by Friday.”
The Modern Solution: Singular “They/Their/Them” In contemporary English, the singular “they,” “their,” and “them” is widely accepted and often preferred for referring to a person whose gender is unknown or irrelevant, or for referring to individuals in a gender-neutral way. This is the most practical and inclusive fix.
Correct (modern and preferred): “Each student must bring their own lunch.”
Correct (modern and preferred): “Every employee should submit their report by Friday.”
Correct (modern and preferred): “A student should always do their best.”
When the Antecedent is Plural: This is usually the simpler case.
Correct: “The students brought their books.”
Correct: “My friends are arriving soon; they are bringing snacks.”

The key is to ensure the pronoun logically connects to its antecedent without ambiguity.

Unclear Pronoun Reference: The Mystery Meat of Meaning

This is perhaps the most frustrating type of pronoun error for a reader. When it’s not immediately clear which noun a pronoun is referring to, the sentence breaks down.

The Mistake: Imagine reading: “Sarah told Jessica that she was coming to the party.” Who is “she”? Sarah or Jessica? You have no way of knowing from the sentence alone, and that uncertainty disrupts the flow of information.
The Fix: Rephrase the sentence to make the reference explicit.
Correct: “Sarah told Jessica, ‘I am coming to the party.'” (If Sarah is speaking)
Correct: “Sarah told Jessica, ‘You are coming to the party.'” (If Sarah is informing Jessica that Jessica is coming)
Correct: “Sarah told Jessica that Sarah was coming to the party.” (Less elegant, but clear)
Correct: “Sarah told Jessica that Jessica was coming to the party.”
Avoid Ambiguous “This,” “That,” “Which,” “It” Similar to the above, using demonstrative pronouns like “this,” “that,” and “which,” or the pronoun “it,” without a clear, preceding noun can lead to confusion.
The Mistake: “The company launched a new product, but it was met with negative reviews.” What is “it”? The product or the launch?
The Fix: Be specific.
Correct: “The company launched a new product, but the product was met with negative reviews.”
Correct: “The company launched a new product, but the launch was met with negative reviews.”
Correct: “The company launched a new product. This product was met with negative reviews.”

Always ask yourself: “If someone who knows nothing about this situation read this sentence, would they understand exactly what pronoun is referring to?” If the answer is no, revise.

Comma Chaos: Punctuation Predicaments and Pauses

The comma is perhaps the most versatile, and consequently, the most misused, punctuation mark. It’s responsible for creating pauses, separating items in lists, and clarifying relationships between clauses. When commas are misplaced, omitted, or overused, the meaning of your sentences can be dramatically altered, or worse, become nonsensical. You want your commas to guide your reader, not trip them up.

The Comma Splice: When Two Sentences Become One (Incorrectly)

This is a cardinal sin of punctuation. A comma splice occurs when you join two independent clauses (sentences that could stand alone) with only a comma.

The Mistake: “The weather was beautiful, we decided to go for a hike.” Both “The weather was beautiful” and “we decided to go for a hike” are complete thoughts. Joining them with just a comma creates a comma splice.
The Fix: You have several options:
Use a period: Separate the independent clauses into two distinct sentences.
Correct: “The weather was beautiful. We decided to go for a hike.”
Use a semicolon: A semicolon can join two closely related independent clauses.
Correct: “The weather was beautiful; we decided to go for a hike.”
Use a comma and a coordinating conjunction: The acronym FANBOYS (For, And, Nor, But, Or, Yet, So) can help you remember these conjunctions.
Correct: “The weather was beautiful, so we decided to go for a hike.”
Correct: “The weather was beautiful, and we decided to go for a hike.”

Commas in Lists: The Oxford Comma Debate

When you have a series of three or more items, commas are used to separate them. But there’s a little debate about the final comma before the “and” or “or.”

The Mistake: Omitting commas between items in a list, or sometimes omitting the final “Oxford” comma can lead to ambiguity. Consider: “I love my parents, Donald Trump and Lady Gaga.” Without an Oxford comma, it sounds like your parents are Donald Trump and Lady Gaga, which is probably not what you intend!
The Fix: The generally accepted best practice for clarity and consistency is to use the Oxford comma (also known as the serial comma). This is the comma that appears before the final coordinating conjunction (and, or) in a list of three or more items.
Correct: “I love my parents, Donald Trump, and Lady Gaga.” (Now it’s clear I love three distinct entities.)
Correct: “The grocery store sells apples, bananas, and oranges.”
Consistency is Key: Even if you choose not to use the Oxford comma, be consistent throughout your writing. However, for professional and academic writing, the Oxford comma is highly recommended to avoid potential misinterpretations.

Commas with Introductory Elements

When a sentence begins with an introductory word, phrase, or clause, it’s often followed by a comma to separate it from the main part of the sentence.

The Mistake: Forgetting the comma after an introductory element can make the sentence harder to read. “After the long meeting everyone was tired.”
The Fix: Place a comma after introductory elements.
Correct: “After the long meeting, everyone was tired.”
Correct: “Unfortunately, the train was delayed.”
Correct: “To understand this concept, you must practice.”
Correct: “If you are going to the store, please pick up some milk.”

For very short introductory adverbs (like “now” or “then”), the comma is sometimes optional, but it’s rarely wrong to include it for clarity.

Commas with Nonessential Clauses and Phrases

When a clause or phrase provides extra information but is not essential to the core meaning of the sentence, it should be set off by commas.

The Mistake: Omitting commas around nonessential elements can make a sentence appear to be defining the noun, when it’s actually just adding supplementary detail. “My brother who lives in California is visiting next week.” This implies you have multiple brothers, and the one living in California is the one visiting.
The Fix: Use commas to surround nonessential elements.
Correct: “My brother, who lives in California, is visiting next week.” (This implies you have only one brother, and he happens to live in California.)
Essential vs. Nonessential: The key difference lies in whether removing the clause or phrase changes the fundamental meaning of the sentence.
Essential (no commas): “Students who cheat will be punished.” (This specifies which students will be punished – only those who cheat. The clause is essential.)
Nonessential (commas): “Students, who generally want to succeed, will study hard.” (This provides additional information about students in general but doesn’t define them. The clause is nonessential.)

The Great Homophone Hassle: Confusing “There,” “Their,” and “They’re” (and More!)

Homophones are words that sound alike but have different spellings and meanings. This is a persistent tripping hazard for many writers, as hearing the word can lead you to write the wrong one. You’ve encountered these, haven’t you? The subtle sound that leads to a glaring spelling error.

The Undisputed Trio: “There,” “Their,” and “They’re”

This is the legendary quartet of confusion, the trinity that haunts countless essays, emails, and social media posts. Mastering these three is a significant step toward grammatical prowess.

The Mistake: The most common error is using “there” when you mean “their” or “they’re,” or vice-versa. For example: “There going to the park.” Or, “Their is a new movie out.”
The Fix: Break down each word and its function:
“There”: This word primarily refers to a place or is used to introduce a sentence (similar to “here”).
Place: “Put the book over there.”
Introduction: “There is a problem.” “There are many solutions.”
“Their”: This word is a possessive pronoun. It indicates that something belongs to them.
Correct: “The students left their bags in the classroom.” (The bags belong to the students.)
Correct: “The company announced their new policy.” (The policy belongs to the company.)
“They’re”: This is a contraction of “they are.” If you can substitute “they are” and the sentence still makes sense, then “they’re” is the correct choice.
Correct: “They’re happy to be here.” (Substitute: “They are happy to be here.”)
Correct: “I hope they’re enjoying the party.” (Substitute: “I hope they are enjoying the party.”)

Mnemonic Device: Think of “their” as having “heir” in it, implying something inherited or owned. “There” has “here” in it, pointing to a location. “They’re” has the apostrophe like other contractions (“it’s,” “you’re”).

“To,” “Too,” and “Two”: A Simple Sound, Three Meanings

Another common trio that can cause headaches.

The Mistake: Using “to” when you mean “too,” or “two” when you mean “to.” For example: “I want to go to.” Or, “I too want to go.”
The Fix:
“To”: This is a preposition that indicates direction or purpose, or it’s part of an infinitive verb.
Direction: “Go to the store.”
Purpose: “I’m here to help.”
Infinitive: “I want to see the movie.”
“Too”: This word means “also” or “excessively.”
Also: “I want to go, too.”
Excessively: “This coffee is too hot.”
“Two”: This is simply the number 2.
Correct: “I have two cats.”

Mnemonic Device: “Too” has an extra “o,” suggesting “also” or “extra.”

“Your” and “You’re”: The Ever-Present Confusion

This pair is directly related to the apostrophe discussion earlier, but it bears repeating due to its prevalence.

The Mistake: Confusing possessive “your” with the contraction “you’re.” For example: “Your going to love this!”
The Fix:
“Your”: This is a possessive pronoun, indicating ownership.
Correct: “Is this your coat?” (The coat belongs to you.)
Correct: “Please check your email.” (The email belongs to you.)
“You’re”: This is a contraction of “you are.” If you can substitute “you are” and the sentence still makes sense, use “you’re.”
Correct: “You’re welcome.” (Substitute: “You are welcome.”)
Correct: “I know you’re going to be fine.” (Substitute: “I know you are going to be fine.”)

The apostrophe in “you’re” signals that letters are omitted, just like in “it’s” or “they’re.”

“Its” and “It’s”: A Recap for Reinforcement

<br />

We covered this in the apostrophe section, but as it’s a homophone issue, it deserves a final mention here for emphasis.

The Mistake: Using “its” to mean “it’s” (it is/it has), or vice-versa.
The Fix:
“Its”: Possessive. The thing belongs to “it.”
Correct: “The cat licked its paw.”
“It’s”: Contraction of “it is” or “it has.”
Correct: “It’s raining outside.” (It is raining).
Correct: “It’s been a long day.” (It has been a long day).

Diction Dilemmas: Word Choice Woes and Clarity Crescendos

Beyond the mechanics of grammar, the words you choose to convey your message are crucial. Using the wrong word, even if it sounds similar to the correct one, can change your meaning entirely, confuse your reader, or simply make your writing sound less professional. You want your diction to be precise and impactful.

Confusing Similar-Sounding Words: The “Affect” vs. “Effect” Enigma

This is a perennial favorite for grammar vexation. Many words in English sound alike or are spelled similarly but have distinct meanings and grammatical roles.

The Mistake: The most common offender is the “affect” vs. “effect” pair. Many writers use them interchangeably, but they are fundamentally different.
The Fix:
“Affect” (verb): To influence or to produce a change in something.
Correct: “The drought will affect crop yields.” (The drought will influence crop yields.)
Correct: “His positive attitude affected everyone in the room.” (His attitude influenced everyone.)
“Effect” (noun): The result of an influence or change.
Correct: “The drought had a severe effect on crop yields.” (The result of the drought was severe.)
Correct: “The new policy had a positive effect on employee morale.” (The result of the policy was positive morale.)
“Effect” (verb – less common): To bring about or accomplish.
Correct: “The manager aimed to effect change within the department.” (To bring about change.)

Mnemonic Device: Think of “Affect” as an Action (verb), and “Effect” as an End result (noun).

Misused “Than” vs. “Then”

Another pair that often gets mixed up, leading to awkward phrasing.

The Mistake: Using “than” when comparing things, and “then” when indicating sequence or time. For example: “He is taller then me.”
The Fix:
“Than”: Used for comparisons.
Correct: “He is taller than me.”
Correct: “This book is more interesting than the last one.”
“Then”: Used to indicate sequence, time, or consequence.
Correct: “First, we will discuss the agenda, and then we will brainstorm ideas.”
Correct: “If you finish your homework, then you can watch TV.”

Mnemonic Device: “Than” is for comparison (think “a” as in “a comparison”). “Then” is for time (think “e” as in “eventually” or “sequence”).

“Literally” and “Figuratively”: The Common Misuse

The word “literally” has become notorious for being used hyperbolically, losing its true meaning.

The Mistake: Using “literally” to mean “figuratively” or “very.” For example: “I literally died of laughter.” Unless you are a ghost, you did not literally die.
The Fix: Use “literally” only when you mean something happened in a literal, actual sense.
Correct: “The fire literally burned down the entire building.” (The building was actually burned.)
Correct: “He was so tired, he literally fell asleep standing up.” (He actually fell asleep.)
When to Use “Figuratively” or “Very”:
Correct: “I was so embarrassed, I figuratively died.”
Correct: “That joke was very funny.”

While common usage is shifting, for clear and precise writing, it’s best to reserve “literally” for its true meaning.

“Imply” vs. “Infer”: Understanding the Sender and Receiver

These two words describe related but distinct actions in communication.

The Mistake: Confusing who is doing the implying and who is doing the inferring. For instance, saying “I inferred from his tone that he was angry” when you actually mean “His tone implied he was angry.”
The Fix:
“Imply” (to suggest indirectly): This is what the speaker or writer does.
Correct: “Her silence implied disagreement.” (Her silence suggested disagreement.)
Correct: “The politician’s speech implied support for the new bill.”
“Infer” (to deduce from evidence): This is what the listener or reader does.
Correct: “From her silence, I inferred disagreement.” (I deduced disagreement from her silence.)
Correct: “We inferred from the data that the market was growing.”

Mnemonic Device: Imply is what the Messenger does. Infer is what the Investigator (or reader) does.

Conclusion: The Path to Polished Prose

Navigating these common grammar pitfalls isn’t about achieving an unattainable perfection; it’s about enhancing the clarity, credibility, and impact of your writing. By understanding the rules, practicing diligently, and being mindful of these frequent errors, you can transform your everyday communication into polished prose that captivates and convinces your audience. Keep these fixes at your fingertips, and you’ll be well on your way to mastering the nuances of English grammar.
