spearhead
UK: ˈspɪəhed | US: ˈspɪrhed
n. the pointed head of a spear
vt. to lead or initiate (an attack, movement, or project)
The word "spearhead" combines "spear," derived from Old English spere (a thrusting weapon), and "head," from Old English hēafod (top or foremost part). Literally, it refers to the sharp tip of a spear. By metaphorical extension, it evolved into a verb meaning "to lead or pioneer," as the spearhead is the first part to penetrate or initiate action. This dual meaning reflects both physical and abstract leadership roles.
