Why this word is great

ONRUSH — [Noun] A powerful, often sudden, forward movement or flow, or an aggressive assault. From the English prefix on- (expressing motion or direction toward) + rush (to move or act with great haste or violence), modeled after the older verb phrase 'rush on'; compare Middle English onresen (to rush upon, attack) and Old English onrǣsan (to rush, rush on) and onrǣs (an onrush, assault). Unlike “onslaught,” which foregrounds destructive impact, or “flow,” which suggests placid continuity, an onrush is the pure vector of precipitating force. It is the roar of meltwater breaching a winter dam, the deafening forward surge of a stadium crowd, the silent, terrifying momentum of headlights in a rearview mirror—the world’s brief, convincing argument that everything is moving irrevocably forward.

noun

An aggressive assault.“He caught Grendel's right hand, and still without rising from his bed, stopped the monster's onrush.”

verb

To rush or flow forward forcefully.“Werner’s run had created the space and Havertz got there before the onrushing Ederson, catching a little break off the goalkeeper before rolling it into the empty net.”
