vertebra
UK: ˈvɜːtɪbrə | US: ˈvɜːrtɪbrə
n. any of the small bones forming the spinal column in vertebrates
The word "vertebra" originates from Latin vertebra, meaning "joint" or "a turning point," derived from vertere ("to turn"). This reflects the flexible, segmented structure of the spinal column, where each bone (vertebra) allows movement. The suffix -a marks it as a singular noun. Over time, the term specialized in anatomy to denote the individual bones of the spine, emphasizing their role in enabling spinal rotation and flexibility.
