The word "rain" traces back to Old English regn or rēn, derived from Proto-Germanic regna-, meaning "rain." This term is further linked to the Proto-Indo-European root reg- ("moist, wet"), which also gave rise to words like "irrigate" and "rigid" (via Latin). Unlike compound words, "rain" is monomorphemic—its spelling and meaning have remained cohesive throughout its evolution, reflecting its ancient roots as a core natural phenomenon.
