One minute conceptual poetry. The word nostalgia is learned formation of a Greek compound, consisting of νόστος

(nóstos), meaning "homecoming", a Homeric word, and ἄλγος (álgos), meaning "pain"or "ache", and was coined by a 17th-century medical student to describe the anxieties 

displayed by Swiss mercenaries fighting away from home. Described as a medical condition—a form of melancholy—in the Early Modern period, it became an important trope in Romanticism.
