Learning English can be a rewarding experience, but it’s not without its challenges. Intermediate English learners often find themselves grappling with various grammar rules and nuances as they strive to improve their language skills. In this article, we will explore some of the most common grammar mistakes that intermediate-level English learners make and provide guidance on how to avoid them.

Mixing up Verb Tenses

One of the most frequent grammar mistakes is the incorrect use of verb tenses. Intermediate learners may inadvertently shift between past, present, and future tenses within a single sentence or paragraph. To avoid this, pay close attention to the timeframe of your narrative and choose the appropriate tense accordingly. Consistency is key!

Mistaking Articles (a, an, the)

Articles can be tricky for learners because their usage doesn’t always align with the rules of their native language. Remember that “a” and “an” are indefinite articles, used with singular nouns that are not specific, while “the” is a definite article used with specific nouns. Practice is key to mastering article usage.

Neglecting Subject-Verb Agreement

Subject-verb agreement errors occur when the subject and verb do not match in number (singular/plural). For instance, saying, “The team are playing well” should be corrected to “The team is playing well” because “team” is a singular noun. Pay attention to the number of the subject and ensure your verbs agree with it.

Confusing Prepositions

Prepositions can be confusing, as they often have specific usages that vary from language to language. Common preposition mistakes include using “in” instead of “on” or “at,” or vice versa. To improve, practice using prepositions in context, and refer to reliable sources for guidance.

Neglecting Pronoun-Antecedent Agreement

Pronoun-antecedent agreement errors arise when the pronoun does not match its antecedent in gender or number. For example, saying, “Each student should bring their textbook” should be corrected to “Each student should bring his or her textbook.” Be mindful of gender-neutral options like “they” when appropriate.

Overusing or Misplacing Commas

Intermediate learners often struggle with commas, either using too many or too few. Commas should be used to separate items in a list, set off introductory phrases, and clarify sentence structure. Practice using commas correctly to enhance your writing’s clarity and readability.

Neglecting Capitalization Rules

Capitalization rules in English can be challenging, especially when learners are accustomed to different rules in their native language. Always capitalize the first word of a sentence, proper nouns (names of people, places, and things), and titles, while keeping the rest of the words in lowercase.

Using Double Negatives

In English, two negatives often make a positive, so using double negatives can lead to confusion. For example, saying, “I don’t need no help” should be corrected to “I don’t need any help” or “I don’t need help.” Stick to one negative to convey your message clearly.


Intermediate-level English learners should not be discouraged by these common grammar mistakes, as they are a natural part of the learning process. With consistent practice, exposure to authentic English materials, and a commitment to improvement, these errors can be gradually eliminated. Remember that language learning is a journey, and each mistake is an opportunity to grow and refine your skills. So, keep learning, keep practicing, and soon, you’ll find yourself making fewer and fewer of these common grammar mistakes.
