Grammar Mistakes to Avoid when Writing in English

Good news! You don’t have to speak perfect English all the time when talking with a native speaker, because they don’t really mind. That should lift some pressure on your shoulder, but writing is a completely different skill from speaking. When you write, be careful in your choice of words because once they’re written down, it’ll be difficult taking them back. Here are some common grammar mistakes non-native speakers commit when writing in English.


1. Misusing or not using Apostrophe

We see this a lot. Its a common mistake in most essay’s. Oops, did you notice that? The second sentence in this paragraph misused the apostrophe. It should have been written this way: It’s a common mistake in most essays. “It’s” is a contraction of two words = “it” and “is”.

“It’s snowing again outside.”

“It’s not the most pleasant time to go outside.”

“It’s going to happen for sure.”

A contraction is a writing and speech technique that allows you to put together two words for economy and efficiency. You use an apostrophe for this.

She is = she’s

That is = that’s

There is = there’s

What is = what’s

Where is = where’s

It doesn’t always involve “s”. For example:

Does not = doesn’t (place the apostrophe between “n” and “t”)

You are = you’re

Did not = didn’t

Should not = shouldn’t

That will = that’ll

There will = there’ll

Is not = isn’t

Are not = aren’t

Reminder: Another use for an apostrophe is to show possession:

“My friend’s decision to go out and play didn’t work out.”

“Andrei’s classmates are coming over instead.”

“His classmates’ parents said they could come and play.”

On the other hand, keep in mind that “its” without an apostrophe shows possession:

“Hey, be careful when driving that car. Its brakes aren’t reliable.” (The car’s brakes)

Keep in mind as well that you don’t need an apostrophe when pluralizing nouns.

Piano’s (possessive), pianos (plural)

Flower’s (possessive), flowers (plural)

Horse’s (possessive), horses (plural)


2. Placing the Wrong Article

An article is that little word you always see before a noun or an adjective that precedes a noun. There are only three articles in the English language but they can still be confusing if you are not mindful: a, an, the

Let’s begin with “a” and “an”: Use “a” before a consonant sound (not letter, but sound), and “an” before a vowel sound

A horse (h sound)

An honor (o sound)

An honest person

A person

Now the article “the”: Use this article when describing something unique or before a noun that both you and your reader are familiar with.

Something unique:

The sun

The Appalachian trail

The first man on the moon

Something both you and your reader are familiar with:

“Are you going to the ball?” (There are no other ball being discussed here except the one you and your reader already knows about.)

“You should see the game on Saturday.”

“Our teacher already released the results.”

Note: Most countries with a plural name are preceded with “the”.

The United States of America

The United Kingdom

The United Arab Emirates

The Netherlands

The Philippines

3. Missing Prepositions

Prepositions are tiny words that can be really, really tricky (“to”, “on”, “from”, “in”, “of”, “between”, and so on), but most non-native speakers worry about “to” and “for” because some languages do not have a local equivalent.

Remember to use these prepositions to show the relationship between its object and another word in the sentence. For example:

“Explain to me.”

“I searched for you.”

“I called for you to come but you didn’t come.”

There are more prepositions and more nuances connected to each. Again, prepositions can be tricky. If you wish to learn more about prepositions and any other grammar parts, visit LingualBox.

4. Getting Mixed Up with Homophones

Homophones are words that sound alike when spoken. As mentioned on top of this article, speaking and writing English are two different skills. You could get away with homophones when delivering a speech, but not when writing a composition. Here are some common homophones and what they actually mean:

“I” (personal pronoun), “eye” (part of your face you use for seeing)

“I have one green eye and one blue eye.”

“Ate” (past tense of eat), “eight” (the number)

“I ate dinner at eight o’clock.”

“Flour” (an ingredient for cooking), “flower” (part of a plant)

“She used so much flour to bake a cake shaped like a flower.”

“Affect” (usually a verb that means to change), “effect” (usually a noun that means the result of a change)

“The effect of the earthquake didn’t really affect my family as we live far away.”

“Their” (a possessive pronoun), “there” (a determiner), “they’re” (a contraction of “they are”)

“Look, there it is, their writing assignment, and they’re very happy about it.”

“Buy” (to purchase), “by” (a preposition), “bye” (to say farewell; short for “goodbye”)

“The customer will buy that item posted by the merchant, and before he will leave the store with it, I bet you he will say ‘bye’ to his money.”

“Due” (expected or planned), “do” (to act on something), “dew” (moisture)

“That assignment is due tomorrow so don’t forget to do it. Meanwhile, go outside and check out dew on the plants.”

5.  Pluralizing Incorrectly

One of the first lessons in English is how to pluralize nouns. Some nouns simply need an “s” or “es” in the end while others take on a new form entirely. One of the common mistakes committed by non-native speakers, however, is making uncountable (mass) nouns plural. Some common mass nouns are:

“information”, “water”, “garbage”, “luggage”, “intelligence”, “freedom”, “love”, and so on

Here is a tip: These are either abstract concepts (compassion, anger) or objects in the real world that you cannot count (sugar, salt).



Have you caught yourself committing or struggling with one or some of these mistakes? I bet you have. These are just the common ones. You might also need to work on your punctuations, verb tenses, adjectives and adverbs, and so on.
