shuttlecock

The word 'shuttlecock' is a compound noun formed from two distinct elements. The first part, 'shuttle,' originally meant a missile or projectile, evolving to describe the regular to-and-fro motion of a weaving shuttle, which metaphorically applies to the object's flight. The second part, 'cock,' directly references the male bird, specifically the feathers traditionally used to stabilize its flight, much like the tail feathers on an arrow. Thus, the term literally means a "projectile made with cock's feathers," perfectly describing the essential components and dynamic motion of the badminton object. This combination reflects a practical, descriptive naming logic common in Early Modern English.

Structure: shuttle + cock - shuttle: From Old English scytel ("dart, arrow"), related to the verb to shoot. In this compound, it denotes an object that is propelled back and forth. - cock: From Middle English cok, referring to a male bird. Here, it refers to the feathers, originally from a rooster, used to make the projectile.
