rain-soaked

The compound adjective "rain-soaked" is a transparent and relatively modern formation in English, following a common pattern where a noun ("rain") is combined with a past participle ("soaked") to create a descriptive term. The first element, "rain," has a stable history from its Proto-Germanic root regna-, denoting precipitation. The second element, "soaked," originates from the Old English verb sōcian, meaning to become saturated or steeped in liquid. The literal logic of the word is perfectly clear: it describes something that has been thoroughly drenched or permeated by rainwater, directly combining the source of the wetness with the state it induces.

Structure: rain (water from clouds) + soaked (thoroughly wet) - rain: From Old English regn, rēn (rain), of Proto-Germanic origin, related to Dutch regen and German Regen. It functions as a noun used attributively to specify the cause of the soaking. - soaked: From the past participle of the verb soak, from Middle English soken, from Old English sōcian (to become saturated), of Proto-Germanic origin. It functions as an adjective describing the resulting state of being thoroughly wet.
