What is a "bracket"?

A bracket [ ] is a punctuation mark used in writing to enclose information that clarifies or adds context to a statement. Brackets often indicate modifications or explanations made by someone other than the original author, such as when adding a word for clarity within a quote. In academic writing, they can denote editorial notes or citations. Brackets are also used in mathematics and programming to indicate arrays or lists. They serve to organize information and help readers understand the relationship between different elements in a text.
