What is another word for parenthetical expression?
Pronunciation: [pəɹɪnθˈɛtɪkə͡l ɛkspɹˈɛʃən] (IPA) 
Parenthetical expressions are brief remarks that are enclosed within parentheses. These remarks are often used to provide additional information or clarification to the main text. However, there are several other phrases that can be used to describe this type of writing, such as interjection, aside, or digression. An interjection is a word or phrase that is inserted into a sentence to express strong emotion or surprise. An aside is a remark made by a character in a play that is meant to be heard by the audience but not by other characters. A digression is a temporary departure from the main idea or subject of a piece of writing. Regardless of what it is called, a parenthetical expression serves an essential purpose in making a text more clear and compelling.
