Plural of formation; the action of forming something, or arranged structures such as geological rock layers or military arrangements.
From Latin 'formatio' meaning a shaping or molding, from 'formare' (to form). Extended from physical shaping to abstract arrangements and organized structures by the 16th century.
Whether describing rock layers that took millions of years to form or military units that arrange in seconds, 'formations' captures the human fascination with organized patterns in both natural and artificial systems.
