life-saving
UK: ˈlaɪfˌseɪvɪŋ | US: ˈlaɪfˌseɪvɪŋ
adj. designed or used to preserve life, especially in emergencies
n. an act or means of saving a life
The compound "life-saving" merges "life" (Old English līf, meaning "existence") and "saving" (from Old English safian, "to rescue"). The term emerged in the 18th century, originally describing maritime rescue efforts (e.g., lifeboats). Over time, it broadened to encompass any action or device that prevents death, reflecting its literal logic: "saving life."
