second-floor
UK: ˌsekənd ˈflɔː(r) | US: ˌsekənd ˈflɔːr
adj. located on the floor above the ground level
n. the level of a building immediately above the ground floor
The word "second-floor" is a compound formed by combining "second" (from Latin secundus, meaning "following" or "next in order") and "floor" (from Old English flōr, meaning "ground" or "level of a building"). The term logically denotes the level immediately above the ground floor, reflecting its sequential position in a building's structure. This compound construction is straightforward and mirrors similar ordinal-floor combinations (e.g., "first-floor," "third-floor").
