Which term is used to express emotions in an exaggerated or theatrical way?

The term that best expresses emotions in an exaggerated or theatrical way is "emote." This word specifically refers to the act of expressing one's emotions, often in a way that is heightened or dramatic. It is commonly used in the context of acting or performing, where individuals are required to convey feelings that may not only reflect their own but also resonate with an audience, often through exaggerated expression or delivery.

While "dramatize" is related to portraying a dramatic situation, it does not inherently imply the exaggerated emotional expression that "emote" does. "Express" generally indicates the communication of feelings but lacks the connotation of theatricality. "Act" refers broadly to performing but doesn't specifically capture the notion of emotional exaggeration. Therefore, "emote" is the most suitable choice when focusing on the theatrical and exaggerated aspect of expressing emotions.
