Parentheses vs Brackets by Solomon Osuokam Ogbeh

Parentheses (also known as round brackets) and brackets (also known as square brackets) are punctuation marks used in writing to enclose additional information, clarify meaning, or indicate editorial comments. Understanding their correct usage is essential for clear and effective communication, especially in academic and formal writing.

Parentheses (Round Brackets)

Parentheses are used to provide supplementary information that, if removed, would not alter the main meaning of the sentence. They are also used to indicate remarks by the writer, clarify information, or add afterthoughts.

Examples:

1. Adding Supplementary Information:

·       The festival will be held in Lagos (the largest city in Nigeria) this year.

·       Chinedu’s hobby (playing the guitar) keeps him very busy.

2. Clarifying Information:

·       She finally received her degree (Bachelor of Science) after four years of study.

·       The Nigerian Civil War (1967–1970) had a significant impact on the country.

3. Afterthoughts and Comments:

·       I need to finish my assignment tonight (I should have started earlier).

·       Uche bought a new car last week (a red Toyota Corolla).

Brackets (Square Brackets)

Brackets are primarily used within quoted material to include information that was not part of the original quote. This information can be added for clarification, correction, or comment. Brackets can also be used to indicate editorial or explanatory notes within a text.

Examples:

1. Clarifying Quotes:

·       "He [Governor Adewale] announced new policies for education."

·       "The results [of the experiment] were quite surprising."

2. Adding Missing Information:

·       The research was conducted in several locations [Kano, Ibadan, and Abuja].

·       "She [Dr. Ngozi] was appointed as the head of the department."

3. Editorial Comments:

·       "The conference was a huge success [despite the initial setbacks]."

·       "His speech was inspiring [and surprisingly brief]."

4. Correcting Errors in a Quote:

·       "The law was enacted in 1987 [1977]."

·       "He mentioned that the event will be on Thursday [Friday]."

Differences Between Parentheses and Brackets

1. Usage Context:

·       Parentheses are used to add information, clarification, or afterthoughts to the writer's own text.

·       Brackets are used to modify, clarify, or comment within quoted material or to add editorial notes.

2. Removal Impact:

·       The removal of information within parentheses does not change the fundamental meaning of the sentence.

·       The information within brackets often provides crucial context or corrections to the quoted material.

3. Formality and Purpose:

·       Parentheses are generally more common in everyday writing and informal contexts.

·       Brackets are more formal and are typically used in academic, legal, or professional writing to ensure clarity and accuracy.

Practical Application and Examples

Example Sentences Using Parentheses:

• Nkechi bought new textbooks for her courses (she’s studying for her exams).
• The team's performance this season (considering their previous records) has been outstanding.

Example Sentences Using Brackets:

• The professor stated, "This theory [Darwin's theory of evolution] has changed our understanding of biology."
• The findings of the study [published in the Journal of Medicine] indicated a significant breakthrough.

Exercise

·       She is planning a trip to three cities Lagos, Abuja, and Enugu.

·       The teacher explained the concept with great detail it was very helpful.

·       Amaka loves reading novels by Chimamanda Ngozi Adichie.

·       "The event will be held next Friday."

·       The company’s revenue has increased significantly this quarter.

·       "The witness testified that he saw the suspect at 8:00 PM."

Understanding the correct usage of parentheses and brackets enhances writing clarity and precision. While parentheses add non-essential information and afterthoughts, brackets are crucial for clarifying, modifying, and adding context within quoted material. Mastery of these punctuation marks is vital for students aiming to excel in both academic and professional writing.

By practising the correct use of parentheses and brackets, students can improve their writing skills and ensure their work is clear, accurate, and professional.
