Etymology: This adjective derives from the Latin verb "excitare," meaning "to arouse" or "to call forth." "Excitare" itself is an intensive form of "citare," which means "to set in motion" or "to summon." The prefix "ex-" adds the sense of "out" or "forth," so the original Latin conveyed the idea of stirring up or rousing something outwardly. This root captures the physical sense of awakening or provoking activity. The transition into English came through the influence of French in the late Middle Ages, when many Latin-derived words entered the language. By the 16th and 17th centuries, the verb "excite" had become established in English, initially referring to stirring up emotions, actions, or physical responses. The adjective form, built by adding the suffix "-able," which means "capable of" or "susceptible to," appeared later to describe a person or thing easily aroused emotionally or physically. The suffix "-able" is of Latin origin as well, coming from "-abilis," which was used to form adjectives indicating ability or capacity. Thus, the adjective literally means "capable of being excited." Over time, the sense extended from purely physical arousal to encompass emotional sensitivity and responsiveness, especially to stimuli that provoke enthusiasm, nervousness, or agitation. By the 18th century, the word was commonly used to describe temperament, particularly someone prone to emotional excitement or quick to react. This emotional nuance gradually became the dominant sense, while the physical meaning remained secondary. The term retains a slightly formal tone in modern usage, often employed in psychological or literary contexts to describe a lively or reactive disposition.
