What does side role mean?

Answer 1

A "side role" refers to a secondary or supporting character in a narrative, such as in a film, play, or television show. These characters typically have less screen time and fewer plot responsibilities than the main characters, but they can still be significant in terms of contributing to the story or enhancing the primary characters' development. Side roles often serve to provide comic relief, emotional depth, or critical insights, enriching the overall narrative.
