explorer

Some words arrive dressed like a whole expedition. Explorer is one of them: a Latin verb, explorare, wandered through French and into English, and by the 1680s English had turned it into a person — someone who does the searching, not just the search. The old Latin may have started in the hunting grounds, where a scout shouted or called out to test what was out there; another theory ties it to a word for crying or even flowing, which is wonderfully messy for such a tidy modern noun. That same explosive little ex- shows up in expose and expel, while the business of searching connects it to plain old research and search, cousins that have been snooping around meaning for centuries. So when you call someone an explorer, you are really handing them a linguistic lantern: the person whose job is to go out, call into the dark, and see what answers call back.
