What is parentheses definition?

Parentheses are punctuation marks used to enclose words, phrases, or mathematical expressions within a sentence. They are also known as round brackets, and are shaped like half circles pointing in opposite directions ( ).

Parentheses are used for several purposes in writing, including:

1. To enclose additional information that is not essential to the main sentence, such as an explanation or clarification. For example, "The movie (which was filmed in Canada) won multiple awards."

2. To group words or phrases together for emphasis. For example, "She ran the race (and won!)"

3. To indicate a mathematical expression or equation. For example, "3 + (4 x 2) = 11."

It is important to use parentheses correctly to ensure clarity and accuracy in writing.
