The word "excited" derives from the Latin excitare ("to call forth, rouse"), combining ex- (out) + citare (to set in motion). The root citare also gives us words like "incite" and "citation." Originally used in the 15th century to mean "agitated," it evolved to describe emotional arousal by the 17th century and later adopted in physics (19th century) for atoms in heightened energy states. The suffix -ed marks it as a past participle, functioning adjectivally to describe the state resulting from being "excited."
