Imagine spending hours in the research and writing phases, only to submit your content with grammatical mistakes. You would be embarrassed. Right? Well, that’s exactly what editors and writers—even the most experienced ones—often face throughout their professional journeys.
The issue here isn’t just the errors themselves—it’s the inability to spot them or tell the difference between right and wrong. That’s where we’ll help you out.
In this blog, we’ll highlight the most common grammar mistakes that often confuse writers and can ruin an otherwise great write-up. We’ll explain why each error is incorrect and provide examples to clarify any confusion.
So, let’s begin!
Grammar Mistakes to Avoid in Your Write-ups
1) Who vs. Whom
‘Who’ serves as the subject, which means it performs the action in a clause. However, ‘whom’ is at the receiving end. So, it’s the object in a phrase.
❌ Who did you speak to?
✅ Whom did you speak to?
❌ Whom is calling?
✅ Who is calling?
Hint: If it is replaceable by ‘he’ or ‘she,’ use ‘who.’ But you should use ‘whom’ if ‘him’ or ‘her’ fits better.
2) Which vs. That
Using ‘which’ is correct when you have to add extra detail about something non-essential. However, ‘that’ defines a noun. Therefore, you should only use it for essential information.
❌ The book which I borrowed is great.
✅ The book, which I borrowed yesterday, is great.
✅ The book that I borrowed is great.
3) Lay vs. Lie
Lay and lie often cause confusion because their meanings are quite similar. But ‘lie’ describes the action of resting yourself, whereas ‘lay’ refers to placing an object down.
❌ I am going to lay down for a nap.
✅ I am going to lie down for a nap.
❌ Lie the book on the table.
✅ Lay the book on the table.
Hint: The past participle of ‘lie’ is ‘lay.’
4) Fewer vs. Less
Fewer and less undoubtedly serve the same meanings. But ‘fewer’ is appropriate for countable things, whereas ‘less’ is suitable for non-countable things.
❌ She has fewer patience than her sister.
✅ She has less patience than her sister.
❌ There were less people at the event.
✅ There were fewer people at the event.
5) Farther vs. Further
They both deal with distance. But ‘farther’ is literal, meaning it is for physical distance. ‘Further,’ on the other hand, is figurative, which makes it suitable for conceptual distance.
❌ We will discuss this farther tomorrow.
✅ We will discuss this further tomorrow.
❌ Let’s drive further down the road.
✅ Let’s drive farther down the road.
6) Affect vs. Effect
‘Affect’ is a verb that refers to having influence on something. However, ‘effect’ is a noun, which describes the result of something.
❌ The weather effects my mood.
✅ The weather affects my mood.
❌ The new rule will have a positive affect.
✅ The new rule will have a positive effect.
7) Disinterested vs. Uninterested
‘Disinterested’ means impartial, unbiased, or having no personal involvement. On the other hand, ‘uninterested’ is the antonym of taking an interest in something.
❌ She is disinterested in joining the club.
✅ She is uninterested in joining the club.
❌ The referee was uninterested in fairness.
✅ The referee was disinterested in the outcome.
8) Since vs. Because
‘Since’ has dual roles. It refers to time and an already understood or assumed reason. But you can’t use ‘because’ with time. It is only for situations that emphasize the reason clearly and directly.
✅ It has been years since we met.
✅ Since you’re here early, we can start the meeting.
❌ Since we had no car, we stayed home.
✅ Because we had no car, we stayed home.
9) Different From vs. Different Than
‘Different from’ is suitable for all writing standards that require making a direct comparison. But ‘different than’ occasionally works in informal setups. So, when it does, it is followed by a clause—a phrase that contains a subject and a verb.
❌ This job is different than my last one
✅ This job is different from my last one.
✅ Life in the city is different than it was ten years ago.
10) Bring vs. Take
These verbs both describe motion. But ‘bring’ refers to the movement towards the listener or speaker, whereas ‘take’ highlights the away movement from the location or speaker.
✅ Please bring the book to me.
❌ I’ll bring this package to the post office.
✅ Can you bring the report to me?
❌ Can you take the report to me?
11) Anxious vs. Eager
‘Anxious’ refers to the state of fear, nervousness, worry, or uneasiness. But ‘eager’ is for being ‘enthusiastic’ or ‘excited.’ So, while they’re interchangeable, they mean opposite emotional tones.
✅ He felt anxious about the interview.
❌ I am anxious to start this new role.
✅ I am eager to start this new role.
12) Moot
The meaning of ‘moot’ is different in American and British English. For example, Americans use ‘moot’ when they refer to something irrelevant or unimportant. However, Brits use ‘moot’ as an alternative to something that is debatable or open for discussion.
✅ For British Audience: It is a moot point whether the policy will work.
✅ For American Audience: The issue is moot because the law was repealed.
Pro Tip: Avoid using ‘moot’ as a synonym to eliminate ambiguity.
13) Envy vs. Jealousy
‘Envy’ means wanting something you don’t have. However, ‘jealousy’ indicates the fear of losing someone or something valuable to you. So, they have different emotional roots.
❌ He was envious when his girlfriend talked to her ex.
✅ He was jealous when his girlfriend talked to her ex.
❌ I was jealous of my friend’s promotion.
✅ I was envious of my friend’s promotion.
14) Impactful
‘Impactful’ is an adjective that is quite common in corporate settings. That’s why people often use it imprecisely, like this:
❌ It was an impactful meeting.
So, an excellent practice is to use ‘impactful’ sparingly and replace it with appropriate synonyms, like influential, persuasive, or powerful.
✅ It was a powerful meeting.
15) Irony vs. Coincidence
When two related things happen by chance, use ‘coincidence.’ But if the outcome contrasts with the expectations, use ‘irony.’
❌ It’s a coincidence that the fire station burned down.
✅ It’s ironic that the fire station burned down.
❌ It was ironic that I ran into her twice in one day.
✅ It was a coincidence that I ran into her twice in one day.
16) Nauseous vs. Nauseated
People interchangeably use both these terms in everyday speeches. However, if you’re in the formal sector, use ‘nauseous’ for something that causes nausea and ‘nauseated’ for describing the actual state of feeling sick.
❌ I feel nauseous after the ride.
✅ I feel nauseated after the ride.
✅ That smell is nauseous.
17) Subject–Verb Agreement
A subject and a verb form a clause, phrase, or sentence. But when their pair gets interrupted by collective nouns or multiple phrases, inconsistency between the subject and verb occurs. The following examples better clarify the rights and wrongs of this grammatical error:
❌ A list of items were on the desk.
✅ A list of items was on the desk.
❌ Everyone have finished their work.
✅ Everyone has finished their work.
❌ Here comes the students.
✅ Here come the students.
❌ My friends loves pizza.
✅ My friends love pizza.
❌ The bouquet of roses smell lovely.
✅ The bouquet of roses smells lovely.
❌ The dog bark at strangers.
✅ The dog barks at strangers.
❌ The manager and the assistant was late.
✅ The manager and the assistant were late.
18) Misused Semicolons in Complex Lists
Semicolons don’t just shape beauty; they improve the readability of sentences. But you can’t use them blindly because doing so ruins the meaning.
For instance, the following sentences present the various city-country pairs:
❌ We visited Paris, France; London, England, and Rome, Italy.
✅ We visited Paris, France; London, England; and Rome, Italy.
The first example is wrong because it conveys as if London and Rome are a pair. Another example is of the following name-title pairs:
✅ The speakers were Maria Lopez, CEO of BlueTech; David Kim, Head of Product; and Lila Stone, Marketing Director.
