headway
UK: ˈhɛdweɪ | US: ˈhɛdweɪ
n. progress or forward movement, especially in difficult circumstances
n. the space or time allowed for a vessel to pass ahead of another (nautical term)
The word "headway" combines "head" (Old English hēafod, meaning "front" or "top") and "way" (Old English weg, meaning "path" or "journey"). Originally a nautical term, it referred to the forward motion of a ship. Over time, it broadened to signify any form of progress or advancement, especially against obstacles. The logic is straightforward: moving the "head" (front) forward along a "way" (path) implies steady progress.
