Square Brackets: Definition and Proper Usage Explained

Square brackets, also known as brackets, are a set of punctuation marks that are used in writing to add or alter information in a quote.

They are not used interchangeably with parentheses, which are another type of bracket.

Square brackets come in pairs, with an opening bracket [ and a closing bracket ]. They are often used to enclose words or phrases that are added to a quote to clarify or provide more information.

Here are some examples of how square brackets can be used in writing:

  • To add missing words: “She [said] she would be here at 5 pm.”
  • To clarify a pronoun: “John [Smith] said he would be here at 5 pm.”
  • To correct a mistake: “He said he was born in 1990 [1980].”
  • To provide context: “The company [Microsoft] announced a new product today.”

Square brackets are also commonly used in academic writing to indicate edits or changes made to a quote. This is done to ensure that the original quote is not misrepresented or taken out of context.

The Purpose of Using Square Brackets in Writing

Square brackets, also known as brackets, are a type of punctuation mark that is used to enclose additional information within a sentence. They are used to clarify, modify, or add information to quoted material.

One of the main purposes of using square brackets in writing is to indicate that the words inside the brackets are not part of the original text. Square brackets are used to add information that is not present in the original text, such as clarifications, corrections, or explanations. They can also be used to replace a word or phrase in a quote to make it grammatically correct or to make it more understandable.

Another purpose of using square brackets is to indicate that a word or phrase has been changed or modified from the original text. For example, if you are quoting someone and they use a pronoun like “he” or “she,” but the gender is not clear from the context, you can use square brackets to replace the pronoun with the person’s name.

Square brackets can also be used to indicate that a word or phrase has been omitted from a quote. This is commonly done when a quote is too long or when a specific part of the quote is not relevant to the point being made.

Proper Usage of Square Brackets in Writing

When writing, it is crucial to use square brackets correctly to ensure that your text is clear and easy to understand. Here are some rules to follow when using square brackets in your writing:

  • Correct usage: Square brackets are used to add information to quoted material, clarify nouns and pronouns in a quote that are unclear, translate foreign words or phrases in a quote, or enclose text added to a quote by someone other than the original speaker or writer.
  • Formal writing: In formal writing, such as academic papers or professional documents, it is important to use square brackets correctly and sparingly. Overuse of square brackets can make your writing appear cluttered and confusing.
  • Informal writing: In informal writing, such as emails or personal blogs, square brackets can be used more liberally to add additional information or clarify a point.
  • APA style: If you are using APA style, square brackets are used to indicate changes or omissions in a quote. Use three-spaced periods in square brackets to indicate omitted words, and use square brackets to add words or changes to a quote.

Square Brackets in Formal Writing and Published Content

In formal writing and published content, square brackets are commonly used to add or clarify information within a quote or citation. This is particularly useful when the original text is unclear or when the writer wants to provide additional context for the reader.

One common use of square brackets in formal writing is to indicate editorial changes made to a quote. For example, if a quote contains a grammatical error or a typo, the writer can use square brackets to insert the correct word or letter. This helps to maintain the integrity of the original quote while also ensuring that the reader can understand it correctly.

Square brackets are also used in formal writing to provide additional information or context for the reader. For example, if a quote refers to a person or place that is unfamiliar to the reader, the writer can use square brackets to provide a brief explanation. This helps to ensure that the reader can fully understand the quote and its significance within the larger context of the text.

In published content, square brackets are commonly used to indicate changes or additions to a quote that have been made by the writer or editor. This is particularly important in academic writing, where accurate citations and references are essential.

By using square brackets to indicate changes or additions to a quote, the writer can ensure that their work is accurate and reliable.

Square Brackets in Quotations and Translations

There may be instances where you need to alter the text for clarity or to fit the context of your writing and this is where square brackets come in handy.

Square brackets can be used to add or replace words in a quotation without changing the meaning of the original text. This is particularly useful when you need to clarify a pronoun or add a word that was omitted from the original text. For example, if the original text reads “John said he was going to the store,” but you want to quote only the fact that John is going to the store, you can use square brackets to clarify: “[He] said he was going to the store.”

Square brackets can also be used in translations to indicate words that were added for clarity or omitted from the original text. This is particularly useful when translating from a language like Latin, where the word order and grammar can be quite different from English. For example, if you are translating a Latin text and need to add a word for clarity, you can use square brackets to indicate that the word was not in the original text: “The Latin text reads ‘veni, vidi, vici’ [I came, I saw, I conquered].'”

Using Square Brackets for Clarification

Square Brackets are often used to add additional information or to clarify a statement.

One common use of square brackets is to clarify a quotation by adding information that is not present in the original text. This can include explanations, definitions, or other clarifications that help the reader to understand the meaning of the quote.

For example, if you were quoting a passage from a book that used a pronoun that was unclear, you could use square brackets to clarify the identity of the pronoun. Similarly, if you were quoting a passage that used a technical term that might not be familiar to all readers, you could use square brackets to provide a definition of the term.

Square brackets can also be used to clarify the meaning of a word or phrase that might be ambiguous. For example, if you were writing about a product that had multiple meanings, you could use square brackets to clarify which meaning you were referring to.

Square Brackets in Informal Writing and Social Media

When it comes to informal writing and social media, the use of square brackets can vary depending on the context and platform. Here are some common scenarios where you may encounter square brackets in these settings:

Social Media Posts

In social media posts, square brackets can be used to clarify or add context to a message. For example, if you’re sharing a quote or excerpt from an article, you may use square brackets to indicate any changes or omissions you’ve made to the original text. This can help ensure that your message is clear and accurate.

Informal Writing

In informal writing, such as personal emails or text messages, square brackets can be used to add additional information or clarify a point. For example, if you’re discussing a topic and want to provide some background information, you can use square brackets to indicate that this information is not part of the original message.

Comments

In comment sections on websites or social media platforms, square brackets can be used to add additional context or information to a discussion. For example, if you’re responding to a comment and want to provide some additional information or clarification, you can use square brackets to indicate that this information is not part of the original comment.

The use of square brackets in informal writing and social media can help ensure that your message is clear and accurate. However, always use them appropriately and not overuse them, as this can make your message difficult to read and understand.

Square Brackets vs. Round Brackets 

What is the difference between square brackets and round brackets? In contrast to square brackets, round brackets are used to set off explanatory or supplementary information from surrounding text. They are used to provide non-essential information that may be useful but is tangential to the main meaning of the passage.

Can square brackets be used in place of parentheses? Yes, square brackets can be used in place of parentheses in certain situations. Take note that square brackets and parentheses have different uses and should not be used interchangeably.

Parentheses and square brackets are not the only types of brackets used in writing. Curly brackets, also known as braces, are often used in programming languages to indicate a block of code. Angle brackets, also known as chevrons, are commonly used in HTML coding to enclose tags.

Understanding the proper usage of brackets can help ensure that your writing is clear and accurate.
