Good grammar is essential for clear communication. It helps you express your ideas effectively and makes your writing look professional. Many people, even native English speakers, struggle with good grammar. In this article, I’ll share 25 common grammar mistakes that you should avoid to improve your writing.
1. Their, There, They’re Confusion
These words sound the same but have different meanings. “Their” shows possession, “there” indicates a place, and “they’re” is short for “they are.” Many people mix these up in writing. Using the wrong one can make your sentence confusing or change its meaning.
2. Your vs. You’re
“Your” shows possession, while “you’re” is short for “you are.” Using the wrong one is a common mistake that can make your writing look sloppy. It’s important to double-check which one you’re using. This mistake is easy to fix once you understand the difference.
3. Its vs. It’s
“Its” shows possession, while “it’s” is short for “it is” or “it has. ” This is a tricky one because usually, an apostrophe shows possession. In this case, “it’s” is always a contraction. Remember, if you can replace the word with “it is” or “it has”, use “it’s”.
4. Using Apostrophes for Plurals
Apostrophes are used for contractions and to show possession, not to make words plural. Adding an apostrophe to a plural word is a common mistake. For example, “apple’s” is incorrect when talking about more than one apple. The correct plural is simply “apples”.
5. Affect vs. Effect
“Affect” is usually a verb meaning to influence, while “effect” is usually a noun meaning result. This pair often confuses writers. A good trick is to remember that “affect” is an Action, and they both start with “A.” If you’re talking about the result, use “effect”.
6. Could of, Would of, Should of
These are incorrect. The correct phrases are “could have”, “would have”, and “should have”. The confusion comes from the contracted forms “could’ve”, “would’ve”, and “should’ve”, which sound like “could of”, etc. Always use “have” in these phrases, not “of.”
7. Fewer vs. Less
Use “fewer” for things you can count, and “less” for things you can’t. For example, “fewer apples” but “less water.” A good rule of thumb is if you can use a number before the noun, use “fewer.” If you can’t, use “less”.
8. Who vs. Whom
“Who” is used as the subject of a sentence, while “whom” is used as the object. A simple way to remember is to answer the question with “he” or “him.” If “he” fits, use “who”. If “him” fits, use “whom”.
9. i.e. vs. e.g.
“i.e.” means “that is” or “in other words,” while “e.g.” means “for example.” Many people use these interchangeably, but they have different meanings. Use “i.e.” when you want to clarify something and “e.g.” when you want to give examples.
10. Run-on Sentences
A run-on sentence is when two or more independent clauses are joined without proper punctuation or connecting words. This can make your writing hard to read and understand. To fix a run-on, you can split it into separate sentences, use a semicolon, or add a conjunction.
11. Dangling Modifiers
A dangling modifier is a word or phrase that modifies a word not clearly stated in the sentence. This can lead to confusion or unintentionally funny sentences. To fix this, make sure the subject being modified is clearly stated and close to the modifier.
12. Passive Voice Overuse
Passive voice isn’t always wrong, but overusing it can make your writing weak. In passive voice, the subject receives the action instead of doing it. Active voice is usually clearer and more direct. Try to use an active voice most of the time to make your writing stronger.
13. Subject-Verb Agreement
The subject and verb in a sentence must agree in number. If the subject is singular, the verb must be singular. If the subject is plural, the verb must be plural. This can get tricky with compound subjects or when words come between the subject and verb.
14. Misplaced Modifiers
A misplaced modifier is a word or phrase that is separated from the word it modifies. This can create confusion or change the meaning of your sentence. To fix this, place the modifier next to the word it’s meant to describe.
15. Then vs. Than
“Then” is used to express time or sequence, while “than” is used for comparisons. Many people mix these up because they sound similar. Remember, if you’re comparing things, use “then.” If you’re talking about time, use “then.”
16. Comma Splices
A comma splice happens when you join two independent clauses with just a comma. This is incorrect and can make your writing look unprofessional. To fix a comma splice, you can use a period, semicolon, or add a coordinating conjunction after the comma.
17. Double Negatives
Using two negative words in the same sentence creates a double negative. This is incorrect in standard English and can confuse your readers. Instead of using two negatives, use one positive word to express your meaning clearly.
18. Me, Myself, and I
Many people use “myself” when they should use “me” or “I.” “Myself” is a reflexive pronoun and should only be used when you’re both the subject and object of a sentence. Use “I” as the subject and “me” as the object of a verb or preposition.
19. Lie vs. Lay
“Lie” means to recline or rest, while “lay” means to put or place something. The confusion often comes from their different forms. “Lie” becomes “lay” in the past tense, while “lay” becomes “laid.” Remember, if there’s a direct object, use “lay.”
20. Between vs. Among
Use “between” when referring to two distinct items or people. Use “among” when referring to three or more things or when the items are part of a group or mass of objects. This distinction helps make your writing more precise and correct.
21. Irregardless
“Irregardless” is not a standard word. The correct word is “regardless”. “Irregardless” is considered nonstandard because of the redundant negative prefix “ir-.” Using “irregardless” can make your writing look unprofessional.
22. Could Care Less
The correct phrase is “couldn’t care less”. “Could care less” implies that you do care at least a little. If you want to express that you don’t care at all, use “couldn’t care less.” This is a common mistake in spoken English that often carries over into writing.
23. Literally
“Literally” means actually or without exaggeration. Many people use it for emphasis when they mean “figuratively.” Overusing “literally” or using it incorrectly can weaken your writing. Only use “literally” when something is actually true.
24. Ending Sentences with Prepositions
While not always wrong, ending sentences with prepositions can sometimes make your writing less formal. In formal writing, try to rephrase sentences to avoid ending with prepositions. However, in casual writing or speech, it’s often acceptable.
25. Alot vs. A Lot
“Alot” is not a word. The correct term is “a lot”, which means “many” or “much”. This is a common spelling mistake that can make your writing look unprofessional. Always write it as two separate words: “a lot.”
