50 Grammar Rules: Stop Making These Mistakes in College

Introduction

In the academic realm, writing prowess is not merely an accessory, but a cornerstone for success. Clear, concise, and grammatically sound writing not only facilitates effective communication but also serves as a reflection of a student’s intellectual rigor and professional acumen. This blog post delves into 50 essential grammar rules that every college student should internalize. Whether you’re grappling with punctuation intricacies, navigating the nuances of sentence structure, or struggling to refine word choice, this comprehensive guide aims to equip you with the knowledge necessary to elevate your academic writing to new heights.

1) Subject-Verb Agreement

• Rule: The subject of a sentence must always agree with its verb in number (singular or plural). This fundamental principle ensures grammatical harmony and clarity.
• Example:
  • Correct: The student studies diligently.
  • Incorrect: The students study diligently.
  • Explanation: The singular subject “student” requires the singular verb “studies.” Conversely, the plural subject “students” necessitates the plural verb “study.”

2) Pronoun-Antecedent Agreement

• Rule: Pronouns must consistently reflect the gender, number, and person of the noun they refer to (the antecedent).
• Example:
  • Correct: The teacher praised her students.
  • Incorrect: The teacher praised his or her students. (While technically correct, this can be cumbersome. Consider rephrasing: “The teachers praised their students.”)
  • Explanation: The pronoun “her” clearly and accurately reflects the singular, female antecedent “teacher.”

3) Run-on Sentences: A Barrier to Clarity

• Rule: Run-on sentences occur when two or more independent clauses (complete thoughts) are fused together without appropriate punctuation.
• Consequences: Run-on sentences hinder clarity and can confuse the reader.
• Solutions:
  • Use a period: The game was exciting. The crowd roared.
  • Employ a semicolon: The game was exciting; the crowd roared.
  • Insert a comma and a coordinating conjunction (and, but, or, for, nor, yet, so): The game was exciting, and the crowd roared.
  • Introduce a subordinating conjunction (because, although, since, while): Because the game was exciting, the crowd roared.
• Example:
  • Incorrect: The game was exciting the crowd roared.
  • Correct: The game was exciting. The crowd roared.

4) Comma Splices: A Subtle Yet Significant Error

• Rule: A comma splice arises when two independent clauses are joined solely by a comma. This creates a grammatical disconnect and can obscure the intended meaning.
• Solutions:
  • Use a period: The weather was beautiful; we decided to go for a hike.
  • Insert a semicolon: The weather was beautiful; we decided to go for a hike.
  • Add a coordinating conjunction after the comma: The weather was beautiful, and we decided to go for a hike.
• Example:
  • Incorrect: The weather was beautiful, we decided to go for a hike.
  • Correct: The weather was beautiful; we decided to go for a hike.

5) Mastering the Comma: A Crucial Skill

• Key Uses:
  • Separating items in a series: apples, oranges, and bananas
  • Setting off introductory phrases: After the long day, I was exhausted.
  • Separating nonessential clauses: The book, which I read last week, was fascinating.
  • Setting off appositives: My friend, a talented musician, plays the piano.
• Explanation: Commas are essential for enhancing readability and ensuring clarity within sentences.

6) The Semicolon: A Powerful Tool for Connecting Related Ideas

• Primary Functions:
  • Joining two closely related independent clauses: The storm raged; the trees swayed violently.
  • Separating items in a series that already contain commas: We visited Paris, France; Rome, Italy; and London, England.
• Explanation: The semicolon provides a stronger connection between independent clauses than a comma, while still maintaining a degree of separation.

7) The Colon: Introducing Lists and Important Information

• Key Uses:
  • Introducing a list: The recipe calls for the following ingredients: flour, sugar, and eggs.
  • Introducing a quotation: The professor began the lecture with this quote: “The pen is mightier than the sword.”
• Explanation: The colon signals that important information or a list follows.

8) The Apostrophe: Conveying Possession and Contraction

• Primary Functions:
  • Indicating possession: The student’s book, the children’s toys
  • Forming contractions: can’t, won’t, it’s (it is)
• Explanation: The apostrophe serves distinct grammatical purposes and must be used accurately to avoid confusion.

9) Dangling Modifiers: A Misguided Attempt at Description

• Rule: A dangling modifier is a phrase that modifies a word not explicitly stated in the sentence, leading to grammatical ambiguity.
• Example:
  • Incorrect: Driving down the street, the houses were beautiful. (Who is driving? The houses?)
  • Correct: Driving down the street, I saw many beautiful houses.
• Explanation: Ensure the subject of the sentence is clearly and logically connected to the modifying phrase.

10) Misplaced Modifiers: Out of Place and Confusing

• Rule: A misplaced modifier is a phrase located too far from the word it intends to modify, resulting in a nonsensical or humorous effect.
• Example:
  • Incorrect: I almost ate the entire pizza. (Does this mean you were close to eating the pizza, or did you eat most of it?)
  • Correct: I ate almost the entire pizza.
• Explanation: Position modifiers carefully to ensure they accurately and clearly modify the intended word or phrase.

11) Parallelism: Maintaining Consistency for Clarity

• Rule: When using lists or comparing/contrasting ideas, maintain parallel grammatical structure for clarity and conciseness.
• Example:
  • Correct: I enjoy swimming, running, and biking.
  • Incorrect: I enjoy swimming, to run, and biking.
• Explanation: Parallelism enhances readability and improves the overall flow and coherence of your writing.

12) Active Voice: A Direct and Powerful Approach

• Active Voice: The subject of the sentence performs the action.
  • Example: The student wrote the essay.
• Passive Voice: The subject of the sentence receives the action.
  • Example: The essay was written by the student.
• Explanation: Active voice generally results in more direct, concise, and engaging writing.

13) Tense Consistency: A Foundation for Clear Narration

• Rule: Maintain consistent verb tense throughout a sentence or paragraph unless there is a compelling reason to shift tenses (e.g., to indicate a change in time).
• Example:
  • Correct: I walked to the store and bought groceries.
  • Incorrect: I walked to the store and buy groceries.
• Explanation: Shifting tenses unnecessarily can confuse the reader and disrupt the flow of the narrative.

14) Pronoun Case: Choosing the Right Word

• Subjective Case: I, you, he, she, it, we, they (used as the subject of a sentence)
• Objective Case: me, you, him, her, it, us, them (used as the object of a verb or preposition)
• Possessive Case: my, your, his, her, its, our, their
• Explanation: Correct pronoun usage is crucial for grammatical accuracy and clarity.

15) Sentence Fragments: Incomplete Thoughts

• Rule: A sentence fragment is an incomplete sentence lacking a subject, verb, or both, rendering it grammatically incorrect.
• Example:
  • Incorrect: Because it was raining.
  • Correct: Because it was raining, we stayed inside.
• Explanation: Ensure every sentence expresses a complete thought with a subject and a verb.

19) Spelling and Typos: A Foundation for Professionalism

• Rule: Proofread meticulously for any spelling errors or typos. Even minor errors can detract from the credibility and professionalism of your writing.
• Tools: Utilize spell-check and grammar-check tools as a first line of defense, but always conduct a thorough manual review.
• Explanation: Accurate spelling and proper grammar are essential for effective communication and demonstrate attention to detail.

20) Contractions: A Matter of Tone and Style
