Hidden message, or subtext, refers to the underlying meaning or theme that is not explicitly stated in a piece of communication, such as literature, film, or conversation. It often conveys emotions, motivations, or societal critiques that enhance the overall message. For example, a character's seemingly innocent dialogue may reveal deeper feelings of jealousy or insecurity. Subtext allows creators to engage audiences on multiple levels, encouraging them to read between the lines. This technique is commonly used in works by authors like William Shakespeare or filmmakers like Alfred Hitchcock, where the true intentions of characters or the implications of a scene are subtly woven into the narrative.
