formationerna

Formationerna is the definite plural form of the Swedish noun "formation", used to refer collectively to multiple formations. In Swedish grammar, the definite plural adds the suffix -erna to the base noun, so "formation" becomes "formationerna" when speaking about specific, identified groups or structures.

The term is used across several fields to denote organized shapes, structures or arrangements. In geology and physical geography it commonly describes rock layers, landforms or sedimentary structures that have characteristic shapes and origins. In meteorology and atmospheric sciences it can refer to cloud formations and related patterns.

In military and tactical contexts formationerna denotes unit arrangements, such as troop or vehicle formations designed for movement, defense or ceremony. In biology and medicine the word can describe formations at cellular or tissue levels, including patterns of growth or structural organization.

Formationerna also appears in cultural and social discussions to describe groupings, institutional structures or patterns of organization within societies, organizations and artistic performances (for example, dance or orchestral arrangements). The term traces to borrowings in Swedish from Romance and Latin roots related to "form" and "shaping" and is used broadly to emphasize organized or recognizably patterned configurations.
