The term “excitable” appears in literature as a versatile descriptor of temperament, used to capture both the energy and volatility of characters. In works by Dickens and Poe, for example, it vividly portrays individuals whose nervous or overreactive nature often leads to humorous or dramatic situations—as seen in the “excitable Jew” in Great Expectations [1] and the frequent references in The Raven [2, 3, 4]. Meanwhile, authors like Rousseau and Chekhov employ it to denote a lack of childlike maturity or a tendency toward unwieldy passion in human behavior [5, 6, 7]. Even in treatises on psychology and sociology, “excitable” is utilized to characterize certain groups or witness behaviors, suggesting implications for both personal and societal responses [8, 9, 10, 11]. This usage across genres underscores the term’s broad applicability in conveying spontaneous, sometimes irrational, emotional responses that define a character’s nature or a group’s tendencies.
