What does the term 'three-dimensional character' refer to?

The term 'three-dimensional character' refers to a character that is fully developed and complex, exhibiting various traits, motivations, and growth throughout a narrative. Such characters often display a range of emotions, behaviors, and conflicts, making them relatable and realistic to the audience. This depth can involve backstory, personal struggles, and an evolution over the course of the story, which helps to engage readers and elicit empathy.

Characters that are flat and simplistic, existing solely within dialogue, or those confined to a single role do not offer the same richness or depth that three-dimensional characters possess. This complexity is essential for creating a compelling narrative and for the character's interactions to resonate with the audience on a deeper level.
