Common Grammar Mistakes Made by English Learners

March 21, 2023

English has become an essential language in today’s global world. It is used for numerous activities such as business, communication, and travel. As a result, many people are learning English as a second language. While it can be a challenging process, with time, dedication, and practice most individuals have the ability to achieve proficiency.

Still, the English language can be a tricky one, and it is interesting to note the common errors learners tend to make related to grammar. This article will discuss five such common grammar mistakes frequently made by English learners.

Wrong Preposition

Prepositions are used to indicate certain relationships between words. Wrong prepositions are a very common mistake made by English learners since the usage of prepositions can often be tricky and difficult to remember. For example, one might commonly use the wrong preposition when using the phrase “to speak with someone”; some might mistakenly use “to speak to someone”.

Wrong Tense

Using the incorrect tense when speaking in English is another common mistake made by learners. This could be as a result of the differences between the English language and one’s native language. For example, Spanish speakers often make this mistake when learning English, since in Spanish it is more common to use the present perfect for actions that took place in the past.

Wrong Verb Form

Making certain errors with verbs is common for English learners. This is partly due to the fact that English has several verb forms and its usage of them can be quite complicated. Some learners might forget the difference between irregular verbs and regular verbs, while others might forget that verbs need to agree with the subject in terms of both number and person.

Wrong Verb Agreement

Verb agreement is yet another aspect of grammar that can confuse some English learners. This mistake occurs when the subject and verb do not agree in number or person, for example saying “We are walk” instead of the correct phrase “We are walking”.

Misuse of Articles

Incorrect use of articles such as “a”, “an”, and “the” is a common mistake English learners make. English articles have a complex set of rules when it comes to their usage and many learners struggle to learn these rules. This can lead to errors such as saying “a university” when referring to a particular university or saying “an apple” when referring to a certain apple.

Misplacing Apostrophes

English learners often make common mistakes when using apostrophes. Examples of misplacing apostrophes include using apostrophes to pluralize words, using apostrophes when referring to a single possessive, or omitting an apostrophe when referring to a possessive.

English learners may also misuse apostrophes when writing contractions, leaving out apostrophes when pronouns are repeated and adding an apostrophe when no possessive or contraction is present. By understanding when an apostrophe is required and how to use it correctly, English learners can avoid common grammar mistakes involving apostrophes.

Misunderstanding of Words that Sound The same

A common grammar mistake is misconstruing homophones. Homophones are words that sound the same but have different meanings and can easily be confused. For example, “their”, “there” and “they’re” all sound alike, however, they have different meanings.

Another major error English language learners make is mixing up “to” and “too”. While they sound the same, they are not interchangeable; “to” is used for motion and direction, while “too” is usually used to enhance a statement.

Misusing words like “effect” and “affect” is a common mistake. While they are pronounced the same and look similar, they mean something different; “effect” means the result, while “affect” means to bring about change.

Confusion between “it's” and “its” is a common problem for learners. The contraction “it’s” is used when “it is” is needed, while “its” denotes an object or thing and many other words can seem confusing.


English is a language that has been adopted by many as a second language. Learning it can be a tricky process, and mistakes are often made due to its complexities. We discussed seven of the common grammar mistakes English learners tend to make; wrong preposition, wrong tense, wrong verb form, incorrect verb agreement, and incorrect article usage.
