The act of washing oneself with water falling from above; also means covering or pelting with many things at once.
From Middle English 'shoure,' which referred to rain or a fall of water, related to Old English 'scur.' The word evolved from describing natural rain to describing bathing under artificial water.
The shower as a bathing device is surprisingly modern—most people bathed in tubs until the late 1800s when running water and plumbing made overhead showers practical, yet the word 'shower' had existed for centuries waiting for the technology to catch up.
