quick-moving

The compound 'quick-moving' is a transparent English formation that directly combines two native concepts. The first element, 'quick', originates from the Old English cwic, meaning 'alive' or 'living', a sense preserved in the phrase 'the quick and the dead'. Over time, the vitality associated with being alive became metaphorically linked to speed and briskness. The second element, 'moving', derives from the Latin verb movēre, meaning 'to set in motion', which entered English via Old French. When combined, the literal sense of 'livingly-in-motion' evolved into the modern abstract meaning describing anything characterized by rapid motion or agility, effectively capturing the essence of speed through its constituent parts.

Structure: quick (fast) + moving (in motion) - quick: From Old English cwic (alive, living, animated), of Germanic origin. In this compound, it functions as an adjective meaning 'rapid, swift'. - moving: From the verb 'move', from Old French movoir, from Latin movēre (to set in motion). The suffix '-ing' forms the present participle, which here functions as an adjective meaning 'in the act of motion'.
