Six English Grammar Mistakes You Might Be Making

Let’s take a look at these mistakes – and their corrections.

INCORRECT: Playing sports makes me to feel good.

CORRECT: Playing sports makes me feel good.

When we use the structure “make + someone/something” take an action (meaning to cause that person or thing to take the action), we don’t use the word “to.”

The verb “let” is also like this:

INCORRECT: I let my kids to stay up late.

CORRECT: I let my kids stay up late.

INCORRECT: They got married in October 5th.

CORRECT: They got married on October 5th.

We say “in October” if we say ONLY month, without specifying the day. But if we say the specific date, then we say “on October 5th.” Always use “on” with days: on Monday, on the first of June, on my birthday.

INCORRECT: I bought several stuffs at the store.

CORRECT: I bought several things at the store.

CORRECT: I bought some stuff at the store.

The word “stuff” is considered an “uncountable” noun in English – it is always singular, even when it refers to multiple things. The word “things” is a “countable” noun – it can be singular or plural.

With countable nouns like things, we can use the words manya few, and several.

With uncountable nouns like stuff, we need to use different words: mucha little, and some. (“Some” can be used with countable nouns, too – some books, some tools, etc.)

INCORRECT: I played the piano when I was child.

CORRECT: I played the piano when I was a child.


I played the piano when I was young.

We say “a child,” “a teenager,” and “an adult,” because these are all countable nouns.

“Young” is an adjective, so we do not need to use “a.”

INCORRECT: There’s a cabinet below of the sink.

CORRECT: There’s a cabinet below the sink.

You don’t need “of” with most prepositions of place/location, such as behind, near, under, over, between, etc.

    • My house is near a school.
  • There’s a bridge over the river.

The exceptions are in front ofon top of, and to the right/left of.

  • The pot is on top of the stove.
  • The sink is to the right of the toilet.

INCORRECT: I know every students in the class.

CORRECT: I know every student in the class.


I know all the students in the class.

The noun immediately after “every” must be a singular countable noun. So even though this sentence refers to multiple students, using the word “every” means we must use the singular form, student.

The word “each” is similar, but “each” can be used two ways:

  • The teacher gave a test to each student.
  • The teacher gave a test to each of the students.

We use each + a singular countable noun.

We use each of + the/these/those/my/our/your + plural countable noun.
