In literature, what is a brief remark or comment by a character called?

A brief remark or comment made by a character in literature is referred to as an aside. Asides are typically delivered directly to the audience or to another character, but they are not intended to be heard by all characters on stage. This allows characters to express their thoughts or feelings without other characters being aware of them, creating a deeper understanding for the audience of the character's internal conflict or perspective.

Monologues involve a longer speech by a character, usually revealing their thoughts or feelings in a more extended manner, often directed towards other characters or the audience. Dialogue is a conversation between two or more characters, engaging in back-and-forth exchanges. Soliloquies are similar to asides but are longer and usually delivered by a character alone on stage, disclosing their inner thoughts and emotions in a more elaborate way. These definitions help clarify why a brief remark aligns specifically with the concept of an aside.
