UK: fləʊ | US: floʊ
n. the continuous movement of a liquid, gas, or electricity
vi. to move or proceed smoothly and continuously
n. a steady stream or outpouring (e.g., of ideas)
The word "flow" traces back to Old English flōwan, meaning "to stream or pour." It shares roots with Proto-Germanic flōaną and is related to Dutch vloeien and German fließen. Unlike many modern English words, "flow" has retained its compact, monosyllabic form since its earliest usage, reflecting its fundamental connection to natural movement. Its meaning has expanded metaphorically (e.g., "flow of ideas") while preserving the core sense of smooth, uninterrupted motion.
