The word "underlying" combines "under" (Old English under, meaning "below") and "lie" (Old English licgan, meaning "to rest or be situated"). The suffix "-ing" forms a present participle, turning the verb into an adjective. Originally literal ("lying beneath"), it evolved metaphorically to describe foundational or hidden aspects (e.g., "underlying cause"). In finance, it refers to assets backing derivatives (20th century).
