Why do we use brackets in English?

Brackets in English are used to add additional information, clarify meaning, or indicate an editorial comment within a sentence. They help to include supplementary details without disrupting the flow of the main text. Common types of brackets include parentheses (round brackets) for general notes, square brackets for editorial insertions, and curly brackets for grouping items, though the latter is less common in written English. Overall, brackets enhance clarity and provide context without overwhelming the reader.
