A device or person that finds or pinpoints the location of something, like a GPS tracker or someone skilled at finding things.
From Latin 'locare' (to place) + the agent suffix '-or'. The root evolved through French before entering English in the 19th century to describe anything that determines position or location.
Interestingly, the word 'locator' became hugely popular during the early days of online dating sites and smartphone apps—before that, it was mostly a technical term used in surveying and geology.
