What does formation mean?
Formation refers both to the process by which something comes into being and to the resulting shape, structure, or arrangement of that thing. In its broadest sense, it covers everything from the formation of governments, companies, and friendships to the physical formation of mountains and clouds. The word also has more specialized uses: in military and aviation contexts, a formation describes an ordered pattern — such as a wedge or line — maintained by troops, aircraft, or marching bands, while in geology a formation names a distinct body of rock strata recognized as a mappable unit. Because it bridges abstract processes and concrete arrangements, formation appears constantly in scientific, political, and journalistic writing. Its connotations are neutral: it simply denotes order emerging from process. The related phrase 'in formation' is so established that it functions almost as a word in its own right.
nounThe act or process of forming something, or the manner in which something is formed; also, a structured arrangement of people, aircraft, or things in a set pattern.
- The act or process of forming, creating, or coming into existence.
- The structure, shape, or arrangement into which something has been formed.
- An ordered arrangement of people, aircraft, vehicles, or troops in a prescribed pattern.
- (Geology) A body of rock strata with distinguishing characteristics.

"The jets flew overhead in a diamond formation."
Standard plural; most often seen when referring to multiple geological formations or multiple tactical arrangements.

Every flock of geese you've ever seen flying overhead was flying 'in formation' — a word borrowed straight from Latin that soldiers, pilots, and clouds all share.

Etymology of formation
Formation derives from the Latin formatio, meaning a shaping or fashioning, itself rooted in forma, meaning form, shape, or figure. The English word entered the language from Latin, likely via French influence, in the early modern period, and it retained the core idea of giving shape to something. Its deep connection to forma links it to a large family of English words including conform, reform, transform, formula, and formal — all built on the same ancient notion of shape and pattern.
