Etymology: "Overflight" is a plain compound: the prefix "over-", meaning across or above, joined to "flight", the act of flying. Its parts are both old English words. "Over" descends from Old English "ofer", which carried the same sense of rising above or passing across, and "flight" comes from Old English "flyht", a noun formed from the verb "fly" and tied to the idea of moving swiftly through the air. What makes the word worth a second look is how little its parts have changed. "Flight" has been a noun for centuries, first meaning the act of flying and only later gaining senses like a journey by air or a set of stairs. "Overflight" simply attaches the old preposition-prefix to that noun, so it names a flight that passes over a place rather than landing in it. The meaning follows the grammar: the aircraft's route runs across the territory below, which is why the word is used for flights over borders and terrain for observation or survey.

Synonyms: aerial survey, airborne passage
