doorbell
UK: ˈdɔːbel | US: ˈdɔːrbel
n. a device typically mounted near a door that emits a sound to signal someone's arrival
The word "doorbell" is a straightforward compound of "door" (Old English duru, meaning an entryway) and "bell" (Old English belle, referring to a resonant metal instrument). The term emerged in the early 19th century as electrified signaling devices became common, combining the physical door with the auditory bell to denote a mechanism for announcing visitors. The logic is transparent: a bell associated with a door.
