What Are the Most Common Grammatical Mistakes in Essays?

Writing essays can be challenging, especially when trying to avoid grammatical errors. Grammatical mistakes often weaken the clarity and impact of an essay, affecting its overall quality. For students aiming to submit polished and effective work, understanding and avoiding common grammatical mistakes is essential. This guide explores the most frequent grammar issues found in essays and provides tips to address them, ensuring stronger, more coherent writing.

1. Subject-Verb Agreement Errors

One of the most common grammatical mistakes in essays is subject-verb disagreement. This error occurs when the subject and verb do not match in number (singular or plural). For example:

• Incorrect: "The list of items are on the table."

• Correct: "The list of items is on the table."

In this example, "list" is a singular noun, so it requires the singular verb "is." Paying attention to subject-verb agreement helps maintain sentence clarity. Tools like My Homework market offer valuable resources for students needing extra support in identifying these issues.

2. Incorrect Verb Tenses

Another frequent issue is incorrect or inconsistent verb tense usage. When writing an essay, it’s essential to maintain a consistent tense throughout, unless the context calls for a shift. For example, switching from past to present tense mid-sentence can confuse the reader.

• Incorrect: "She went to the store and buys groceries."

• Correct: "She went to the store and bought groceries."

Maintaining consistency within a paragraph or section helps the reader follow the narrative or argument more easily.

3. Misplaced and Dangling Modifiers

Modifiers add detail to sentences, but misplaced or dangling modifiers can lead to confusion. A modifier should be placed near the word it describes to avoid ambiguity.

• Misplaced Modifier: "She almost drove her kids to school every day."

• Corrected: "She drove her kids to school almost every day."

In the incorrect example, it sounds like she "almost drove," which implies she didn’t drive at all. Rephrasing it clarifies that she drove almost daily. Avoiding these errors enhances the essay’s readability.

4. Comma Splices and Run-On Sentences

A comma splice occurs when two independent clauses are joined with just a comma, while run-on sentences are sentences joined without proper punctuation or conjunctions. Both lead to choppy or confusing sentences.

• Comma Splice: "It’s raining, I forgot my umbrella."

• Corrected: "It’s raining, so I forgot my umbrella."

Breaking up long sentences or adding conjunctions ensures clarity. For students needing further help with punctuation, "My Homework market" offers guides and resources to refine essay-writing skills.

5. Sentence Fragments

Sentence fragments are incomplete sentences that lack a subject, verb, or both, failing to convey a complete thought. Fragments often appear when writers mistakenly believe they have constructed a full sentence.

• Fragment: "Because she was running late."

• Corrected: "She missed the bus because she was running late."

Recognizing and avoiding fragments helps the essay maintain a strong, coherent structure.

6. Incorrect Pronoun Reference

Pronoun reference errors occur when it’s unclear to which noun a pronoun refers. This confusion can cause misunderstandings, making it difficult for readers to follow the argument.

• Ambiguous: "When Sarah and Lisa went to the store, she bought a book."

• Clear: "When Sarah and Lisa went to the store, Lisa bought a book."

Clear pronoun references make it easier for readers to follow along without confusion.

7. Misuse of Apostrophes

Apostrophe misuse is a common grammatical mistake, often seen in possessive nouns or contractions. Misplaced apostrophes can change the meaning of a sentence or create unnecessary ambiguity.

• Incorrect: "The student’s forgot their books."

• Correct: "The students forgot their books."

In this case, "students" should not have an apostrophe because it is plural, not possessive.

8. Incorrect Use of Homophones

Homophones are words that sound the same but have different meanings, like "their," "there," and "they’re." Mixing these words up is a frequent mistake, but it can be avoided with careful proofreading.

• Incorrect: "Their going to the park."

• Correct: "They’re going to the park."

Being mindful of homophones during editing ensures that the intended meaning is conveyed correctly.

9. Confusion with "Who" vs. "Whom"

Many writers struggle with "who" and "whom," but knowing the correct usage can prevent this grammatical error. "Who" functions as a subject, while "whom" acts as an object.

• Incorrect: "Who did you give the book to?"

• Correct: "To whom did you give the book?"

Using "whom" when referring to the object in a sentence helps maintain grammatical accuracy.

10. Overusing Passive Voice

Passive voice makes sentences less direct and often weaker in impact. In academic writing, active voice is generally preferred as it is more straightforward and engaging.

• Passive: "The essay was written by the student."

• Active: "The student wrote the essay."

Opting for active voice where possible enhances the clarity and strength of the writing.

11. Parallel Structure Errors

Parallel structure ensures that related elements in a sentence have the same form. Errors in parallel structure can disrupt the rhythm and readability of an essay.

• Incorrect: "She enjoys reading, cooking, and to swim."

• Correct: "She enjoys reading, cooking, and swimming."

Consistency in structure makes the writing flow more smoothly and improves readability.

12. Improper Capitalization

Incorrect capitalization often appears in essays, particularly with titles, headings, and proper nouns. Knowing when to capitalize words can help avoid this common mistake.

• Incorrect: "He studies at the University of washington."

• Correct: "He studies at the University of Washington."

Proper capitalization reflects attention to detail and professionalism in writing.

13. Confusion with Adjectives and Adverbs

Adjectives modify nouns, while adverbs modify verbs, adjectives, or other adverbs. Mixing these up can lead to awkward phrasing or ambiguity.

• Incorrect: "She ran quick to catch the bus."

• Correct: "She ran quickly to catch the bus."

Using adjectives and adverbs correctly creates a more precise and polished essay.

14. Incorrect Use of "Its" vs. "It’s"

Many writers confuse "its" (possessive form) with "it’s" (contraction for "it is" or "it has"). Mixing these two up can lead to misinterpretation.

• Incorrect: "The cat licked it’s fur."

• Correct: "The cat licked its fur."

Double-checking for this error can help students avoid unnecessary misunderstandings.

15. Inconsistent Formatting and Style

Adhering to a consistent formatting style is important, especially in academic essays. Inconsistencies in font size, margins, and citation format can distract readers from the content. Following a style guide ensures uniformity throughout the paper.
