Common Grammar Error In English and How to Avoid Them
Grammar is critical to the way we communicate in English—whether we’re writing, speaking, or taking formal tests such as IELTS. Having a good vocabulary and the ability to speak fluently do not matter if you have minor grammar errors, which result in confusion, undermine your message, or make you sound less sure of yourself. English learners may know the rules of grammar, but getting them right in real-life situations is a different test altogether. Most students, even at advanced or intermediate levels, commit common grammar errors in English unknowingly. These errors don’t necessarily indicate poor English proficiency—they can be the aftereffect of habits, literal translation of the home language, or an unawareness of some rule. The glad tidings are that with a bit of practice and consciousness, you can readily fix these common grammar errors in English and enhance communication.
In this blog post, we’re going to cover some of the most common grammar error in English that students make and provide you with tips on how to correct them using plain language and examples. From subject-verb concord to the use of articles and mind-bending prepositions, we’ll deconstruct the rules so you can apply them easily.
Whether you’re a student studying for exams, a businessperson who wants to write more effective emails, or an individual who’s looking to enhance your spoken English, omitting even one of the common grammar errors in English can make quite a difference when it comes to being understood.
Let’s take the next step towards better, more confident English. With every error we eliminate, you’ll feel more confident using the language—irrespective of the context.
Subject-Verb Agreement and Common Grammar Errors in English
Subject-verb agreement is one of the most basic rules in English grammar—and also one of the most frequently broken rules in common grammar error in English among learners. The rule itself is straightforward: a singular subject requires a singular verb, and a plural subject requires a plural verb. But it can get complicated with longer sentences or when the subject isn’t directly beside the verb.
Basic Rule Example :
1- She goes to school every day. (Correct – ‘She’ is singular, so the verb ‘goes’ ends in -s.)
2- They go to school every day. (Correct – ‘They’ is plural, so no -s is needed.)
Common Grammar Error In English:
1- He eat lunch at 1 PM. (Incorrect)
2- He eats lunch at 1 PM. (Correct)
Tricky Situations to Watch For :
1- When the subject and verb are separated
1- The quality of the apples are good.
2- The quality of the apples is good.
The subject is “quality,” which is singular—not “apples.”
2- With Collective Nouns
The team is winning. (In American English, collective nouns are usually singular.)
3- Indefinite pronouns (everyone, someone, nobody)
Everyone is welcome.
These are always singular, even if they refer to many people.
Incorrect Tense Usage and Common Grammar Error
Keeping the right tense is crucial for proper communication in English. Tenses assist the listener or reader in knowing when something occurred—past, present, or future. One of the most common grammar errors in English made by learners is confusing verb tenses or employing the wrong form, which can lead to confusion.
Common Grammar Error In English:
I am go to the market yesterday. (Incorrect)
I went to the market yesterday. (Correct – past simple)
She will coming tomorrow. (Incorrect)
She will come tomorrow. (Correct – future simple)
He has went to work. (Incorrect)
He has gone to work. (Correct – present perfect)
Why This Happen
Many learners make tense errors because their first language may not use as many tenses, or the structure may be different. Sometimes learners try to translate directly from their native language, which can lead to confusion.
How to Avoid common Grammar error in English
1- Learn signal words like yesterday, already, now, tomorrow to help you choose the right tense.
2- Practice common sentence patterns like:
I go to school every day. (present simple)
I went to school yesterday. (past simple)
I am going to school now. (present continuous)
3- Make a tense timeline to visualize when to use each tense.
With the right tense, you’re able to express your thoughts confidently and clearly. Whether you’re having a conversation or sending an email, correct tense use demonstrates that you know English grammar.
Misuse of an article
Articles are little words, but they play a big role in English grammar. A lot of learners find it hard to use “a,” “an,” and “the” properly. Getting articles wrong is a common grammatical mistake that can make your sentence awkward or confusing.
Types of Article
Indefinite Articles: "a" and "an"
Used while mentioning something for the first time or something in general.
1- I saw a cat in the garden.
2- She is an engineer.
Definite Article: "The"
Used to refer to specific or previously known things.
1- I saw the cat again.
2- We sat in the car we purchased last week.
Tips to Avoid Article Mistake
1- Use “a” before consonant sounds (a dog, a car).
2- Use “an” before vowel sounds (an apple, an hour).
3- Use “the” when both the speaker and hearer know what is referred to.
Wrong Preposition Usage
Prepositions can be little words such as in, on, at, to, for, but they can totally reverse the meaning of a sentence. For most English learners, it is difficult to select the appropriate preposition because the regulations are not necessarily rational—and they may not directly come from your original language.
Your message may get confusing or you may sound less than fluent if you use the incorrect preposition.
Common Grammar Error In English:
Incorrect: I’m good in English.
Correct: I’m good at English.
Use “good at” to describe skills or abilities.
Incorrect: She is married with a doctor.
Correct: She is married to a doctor.
We say “married to” someone—not “with.”
Incorrect: I will meet you on Monday evening.
Correct: I will meet you on Monday evening OR Monday night is fine, but if you’re exact about time:
I’ll meet you at 6 PM.
Make use of “on” for days, “at” for precise times, and “in” for months, years, and sections of the day.
Tips to Avoid Preposition Mistakes
1- Learn prepositions in phrases, not as single words (e.g., interested in, afraid of, tired of).
2- Read or listen to native English to absorb correct usage naturally.
3- When in doubt, look up the preposition used with a verb or noun in a dictionary.
Double Negatives
A double negative occurs when two negatives are placed in the same sentence. In formal English grammar, this is confusing and is typically incorrect. Double negatives occur frequently in informal language or regional dialects, but they should not be used in formal spoken and written English—particularly in the workplace or academe.
What is double negatives
A double negative is when two negative words (like not, no, never, nothing, nobody, don’t, can’t) are combined in one sentence to make a confusing or wrong meaning.
Common Grammar Error In English:
Incorrect: I don’t need no help.
Correct: I don’t need any help.
“Don’t” is negative in itself—putting “no” on it makes a double negative.
Incorrect: She didn’t say nothing.
Correct: She didn’t say anything.
“Didn’t” and “nothing” are both negative, so they cancel each other out.
Incorrect: We can’t find nobody to help us.
Correct: We can’t find anybody to help us
Why it Matters
Double negatives can confuse your listener or reader. In some cases, they make your sentence mean the opposite of what you intend.
Pronoun Mistakes
Pronouns serve the purpose of eliminating the repetition of nouns and rendering sentences more eloquent. These include words such as he, she, it, they, him, her, them, yours, and theirs. Incorrectly choosing the wrong pronoun or its use in a misplaced location, though, is an easy mistake in English to make—one that could be interpreted with ambiguous meaning or make your sentence ungrammatical.
Common Pronoun Error and How to Fix Them
Subject pronouns: I, he, she, we, they
Object pronouns: me, him, her, us, them
Incorrect: Me went to the store.
Correct: I went to the store.
Incorrect: Her gave me a gift.
Correct: She gave me a gift.
Pronoun-Antecedent Agreement
The pronoun must agree with the noun (antecedent) it replaces in number and gender.
Incorrect: Everyone should bring their books.
Correct: Everyone should bring his or her book. (formal English)
“Everyone” is singular, so the pronoun should be singular too.
Note: In modern English, using “their” as a singular gender-neutral pronoun is becoming widely accepted:
Everyone should bring their book.
Unclear Pronoun Reference
Make sure it’s clear what the pronoun refers to.
Incorrect: When Sarah met Emily, she was happy.
Who was happy—Sarah or Emily?
Correct: When Sarah met Emily, Sarah was happy.
Quick Tips
Always check:
1- Does the pronoun match the noun in number and gender?
2- Is it clear who or what the pronoun is referring to?
Confusion Between Adjectives and Adverbs
One of the most common grammar error in English among English learners is confusing adjectives and adverbs. Although they both describe something, they have different functions in a sentence. Using them incorrectly can make your English unnatural or even alter the meaning of what you’re saying.
Common Grammar Error In English:
Incorrect: He speaks very good.
Correct: He speaks very well.
“Well” is the adverb qualifying how he speaks.
Incorrect: She is beautifully singer.
Correct: She is a beautiful singer.
“Beautiful” is the adjective to qualify the noun “singer.”
Incorrect: They worked slow on the project.
Correct: They worked slowly on the project.
“Slowly” is qualifying the verb “worked.”
Why This Mistake Happen
In most languages, it’s not very distinct between adjectives and adverbs—or both are described by the same word. English usually alters the spelling (generally adding “-ly” to adverbs), so you get used to it.
Quick Tips to Avoid Mistake
Ask yourself: Is the word telling us about a person/things (adjective) or what is being done (adverb)?
If it’s telling us how something is being done, you probably need an adverb

Adverb Placement is the Common Grammar Error in English
Adverbs provide additional information about a verb, an adjective, or even another adverb. Adverbs tell us about how, when, where, how often, or how much something happens. However, when adverbs are misordered in a sentence, it can obscure the intended meaning or sound odd. This is one of the most common problems students face when trying to communicate fluently, whether in speaking or writing.
What is the Right Place for an Adverb
Adverb placement depends on the type of adverb and your intent. There are, however, some common placements:
Before the main verb:
She always arrives on time.
After the verb to be:
He is usually calm.
At the very start or very end of the sentence (usually with time / place):
Yesterday, we went shopping.
We went shopping yesterday.
Common Grammar Error In English:
Incorrect: She speaks English fluently always.
Correct: She always speaks English fluently.
We’ll want to have ‘always’ before the main verb ‘speaks’.
Incorrect: He quickly is running.
Correct: He is quickly running.
When using forms of ‘be’ as an auxiliary verb (like ‘is’) we put adverbs between the auxiliary and main verb.
Incorrect: I go to the gym rarely.
Correct: I rarely go to the gym.
Frequency adverbs (always, never, often, rarely) typically go before the main verb.
Quick Tips to Avoid Mistake
For frequency adverbs, put again before any main verb and after any ‘be’ verbs in use.
Read English language text and be conscious of adverb placement, you’ll start to develop an ear for what sounds right.
