Understanding Common Grammar Mistakes
Subject-Verb Agreement
Subject-verb agreement errors occur when the subject and verb don't match in number (singular or plural). This is one of the most common grammar mistakes in writing.
The group of students were working on their projects.
The group of students was working on their projects.
Even though "students" is plural, the subject is "group," which is singular and requires a singular verb.
Pronoun-Antecedent Agreement
Pronoun-antecedent agreement errors happen when a pronoun doesn't agree with its antecedent in number, gender, or person.
Every student must submit their assignment by Friday.
Every student must submit his or her assignment by Friday.
Since "every student" is singular, traditionally the pronoun should be singular. However, many modern style guides now accept "their" as a gender-neutral singular pronoun.
Run-on Sentences
Run-on sentences occur when two or more independent clauses are joined without proper punctuation or conjunctions.
The research was conclusive the hypothesis was correct.
The research was conclusive; the hypothesis was correct.
Adding a semicolon or conjunction (and, but, or) helps separate independent clauses properly.
Comma Splices
A comma splice happens when two independent clauses are joined with just a comma, which is not strong enough to connect them.
She finished her essay, she submitted it immediately.
She finished her essay; she submitted it immediately.
To fix comma splices, you can use a period, semicolon, or add a coordinating conjunction (and, but, or, so).

Tips for Better Academic Writing
Strong academic writing is clear, concise, and well-organized. Here are some valuable tips to improve your academic papers and essays:
- Plan before you write: Create an outline that organizes your main points and supporting evidence before starting your draft.
- Be specific and precise: Use concrete examples and specific details rather than vague generalizations.
- Maintain an academic tone: Avoid colloquialisms, contractions, and overly casual language in formal academic writing.
- Use transitions effectively: Connect paragraphs and ideas with appropriate transition words to ensure smooth flow.
- Cite sources properly: Always give credit to original sources following the appropriate citation style (APA, MLA, Chicago, etc.).
- Revise and edit thoroughly: Don't submit your first draft—review for content, organization, clarity, and grammar.
