10 Common Grammatical Mistakes in English

November 13, 2019

A large number of English native speakers frequently make grammar mistakes without even realising. For many, this is simply due to a lack of proper teaching when they were at school. Don’t worry, though, help is at hand! We have compiled a list of 10 mistakes people make when speaking and writing in English. Learn them all and you’ll have better grammar than many Brits! Though this guide has been written with an international audience in mind, you can still benefit as a native. Want to know more about our proofreading services? Click here for more information.

1. Could/Should/Would of

This mistake is made because the contracted form of “could have” or “could’ve” sounds like “could of” when you say it out loud. This happens across all three words. 

How not to do it: 

I could of gone to the shop

I should of gone to the shop

I would of gone to the shop

How to do it:

I could have gone to the shop

I should have gone to the shop

I would have gone to the shop

2. There/Their/They’re

Here we have an instance of words that sound the same, but are spelled differently. Use ‘there’ to refer to a place that is not here, but rather, ‘over there’ or to state something e.g. “there are no crisps left”. Use ‘their’ to refer to possession i.e. something belonging to them. Use ‘they’re’ when you want to say ‘they are’. 

How not to do it: 

Their going to be here soon

We should get in touch with they’re parents

Can we use there car?

How to do it:

They’re going to be here soon

We should get in touch with their parents

Can we use their car?

3. It’s/Its

This is another one that often confuses people. You can only use “it’s” when you want to say “it is”, whereas you use “its” when referring to something belonging to something that isn’t masculine or feminine.

How not to do it: 

Its raining outside

The car looks great with it’s new wheels

How to do it:

It’s raining outside

The car looks great with its new wheels

4. To/Two/Too

It’s easy to see why people may get this wrong, but once you understand the difference, it’ll be easy for you. “To” is an infinitive form of a verb, such as “to eat” and can also mean ‘towards’. “Too” means “also” or “as well”. “Two” refers to the number 2.

How not to do it: 

I’m to cold

I’m going two the cinema

He bought too of them

How to do it:

I’m too cold

I’m going to the cinema

He bought two of them

5. Then/Than

This is a very common mistake that we as proofreaders see a lot. To put it simply, “than” is used when you are making a comparison. “Then” is used to indicate something following something else in time e.g. when planning a schedule. 

How not to do it: 

I’ve had more then enough

She was better at it then him

How to do it:

I’ve had more than enough

She was better at it than him

We’ll go shopping first, then we’ll go to the bakery

6. Me/Myself/I

The question of how to refer to oneself causes all manner of conundrums, particularly when referring to another person in the same sentence. When referring to yourself and someone else in a sentence, always put their name first. Choose “me” or “I” by removing their name and seeing which sounds right. You would also use “me” if it comes after a preposition. You only use ‘myself’ if you’ve already use “I” to make you the subject of the sentence. 

How not to do it: 

Me and Bob are going to the cinema tonight

Give it to Bob and I to look after

On behalf of my wife and I

Myself and Bob are going to the football game

How to do it:

Bob and I are going to the cinema tonight

Give it to Bob and me to look after

On behalf of my wife and me

7. Affect/Effect

Affect is a verb – “to affect” – meaning to influence or have an impact on something.

Effect is the noun – “a positive effect” – referring to the result of being affected by something. There is also a verb “to effect”, meaning to bring something about – “to effect a change”. 

How not to do it: 

He waited for the paracetamol to have an affect

They were directly effected by the fire

How to do it:

He waited for the paracetamol to have an effect

They were directly affected by the fire

8. Fewer/Less

It seems like even supermarkets do not know the difference between “fewer” and “less”. “Fewer” refers to items you can count individually, such as supermarket items. “Less” refers to a commodity, such as water or coffee, that can’t be counted individually. 

How not to do it: 

There are less cars in the factory now

You must have 5 items or less to use this isle

How to do it:

There are fewer cars in the factory now

You must have 5 items or fewer to use this isle

Less coffee

9. Your/You’re

Put simply, “your” indicates possession, whereas “you’re” means “you are”. Learn this easy distinction and you’ll never make this mistake again.

How not to do it: 

I don’t know what your talking about

Your looking really nice today

Please try on you’re clothes

How to do it:

I don’t know what you’re talking about

You’re looking really nice today

Please try on your clothes

10. Who/Whom

In short, “who” refers to the subject of a sentence, whereas “whom” refers to the object of a sentence. To help you with this one, “who” and “whom” work in the same way as “he” and “him”. “Who did this? He did” – so “who” is correct. “Whom should I invite? Invite him” – so “whom” is correct.

How not to do it: 

Who shall I invite to my party?

Whom is responsible for organising this?

How to do it:

Whom shall I invite to my party?

Who is responsible for organising this?
