While you’re using great copywriting skills to convince your readers to take a particular action, make sure your content is grammatically correct.

Be careful when using autocorrect while typing. It won’t catch grammar mistakes, because a word may be spelled right and be grammatically incorrect. For example:

Your my favorite dancer.
You’re my favorite dancer.

Both words are correctly spelled.


Here are some common writing mistakes that can weaken the sparkle and credibility of your message.


1. Incorrect subject verb-agreement

If the subject is singular, the verb must be singular.

Example: There is so many great ones.
Correct: There are so many great ones.

Example: Everyone was willing to participate. (This is correct.)



2. Missing commas

How you use commas in a list depends on the specific writing style you follow.

An Oxford, or serial, comma is the last comma in a list. It goes before the word “and.”

Example 1: When you go shopping, be sure to get eggs, milk, bread and peanut butter.
When you go shopping, be sure to get eggs, milk, bread, and peanut butter.

Although there are different schools of thought regarding the use of the Oxford comma, when you want to write a good sentence, it’s proper punctuation to always use commas to separate the multiple items you reference in a list.

Technically, it’s grammatically optional in American English.

Example 2: If the shop is closed when we get there we’ll have to wait until next week.
If the shop is closed when we get there, we’ll have to wait until next week.



3. Apostrophes

Apostrophes are generally used in two instances:

For contractions (I’m planning to go tomorrow, if it’s not raining)

To show possession (Susan’s computer means the computer belongs to Susan)

They’re also used to indicate missing numbers in a year, ’89 for 1989 and ’07 for 2007.



4. Hyphens

Example:

Wrong: my 90 year old grandmother
Right: my 90-year-old grandmother



5. Loose or lose

Loose means not firmly or tightly in place.

Example:

Your shoelace is loose.
He might lose the money.



6. Could of, would of, should of

These are incorrect uses of contractions for I could have, I would have, or I should have.

Correct Example:

I should have gone to the reception, and could have, if Tom had been on time.

Slurring in speech results in the common grammar mistake of substituting of for have.



7. Affect and effect

Affect and effect are often confused, although one is a verb and the other a noun.

Affect is a verb that describes something that causes or influences change. Effect is what happens as a result of the change.

“Here’s a mnemonic: A is for action. Verbs are about action. Affect starts with an A, so it’s a verb.”

Correct Examples:

Not getting enough sleep will adversely affect your health.
The effect of not getting enough sleep is bad health.



8. There, their, they’re

There is a location, their shows possession by more than one person, and they’re is a contraction for they are.

Examples:

We live here not there.
They work there but it’s not their shop.
They’re happy to be home.



9. Your and you’re

Wrong: Your my inspiration.
Correct: You’re my inspiration.

Your is the possessive of you.
You’re is the contraction for you are.



10. Then and than

Use then when referring to time.
Than is used when comparing things.

Example:

I’m going to the library then to the store.
That is better than this one.
