rainstorm
UK: ˈreɪnstɔːm | US: ˈreɪnstɔːrm
n. a heavy fall of rain accompanied by strong winds, thunder, or lightning
The word "rainstorm" is a straightforward compound of "rain" (Old English regn, meaning "precipitation") and "storm" (Old English storm, meaning "violent weather"). It emerged in Middle English as a descriptive term for intense rainfall events. The combination reflects a logical pairing of natural phenomena, where "rain" specifies the type of precipitation and "storm" intensifies its nature. This compounding pattern is common in English for weather-related terms (e.g., snowstorm, thunderstorm).
