Military observation of a region to locate an enemy or ascertain strategic features. Also, a preliminary survey or examination.

Reconnaissance is about gathering preliminary information, often by observation, before a main operation or action. It's about 'knowing again' or 'knowing beforehand' what lies ahead.

The story behind the word. Like many military terms, 'reconnaissance' comes from French. It's derived from the Old French 'reconnoissance,' meaning 'recognition' or 'acknowledgment.' This word is built from the prefix 're-' (again) and 'connaître' (to know), which itself comes from the Latin 'cognoscere' (to know). So, reconnaissance is literally 'to know again' or 'to know beforehand,' perfectly describing the act of surveying an area to gain prior knowledge.
