What does vertebration mean?
Vertebration is a rare noun denoting the formation of vertebrae, the individual bones that make up a vertebral column. It is especially relevant in embryology and comparative anatomy, where the process and timing of vertebral development can distinguish taxa and help explain abnormalities. The word may also be used, more rarely, for the vertebrae or vertebral column considered collectively. In ordinary writing, “spine,” “backbone,” or “vertebral column” will usually be clearer, but vertebration provides a compact term for the developmental process itself. Its unusual sound should not be confused with vertebrate, which names an animal possessing such a backbone, or with a vertebra, which names one bone in the column. The word is formal and technical rather than everyday, and it belongs mainly to scientific, anatomical, and historical discourse. Learning it also illuminates a productive family built on vertebr-, the same root found in vertebra, vertebral, and vertebrate.
nounThe formation or development of vertebrae; more rarely, the vertebrae or vertebral column considered collectively.
- The formation or development of vertebrae.
- The vertebrae or vertebral column considered collectively.
"The embryologist examined the stages of vertebration in the developing embryo."
"The embryologist traced vertebration in the developing embryo."
"Damage to the fossil's vertebration made identification difficult."
The plural is grammatically standard but rarely encountered because the word itself is uncommon.
"The paper compares vertebrations in several embryonic stages."
Spines begin as a construction project: vertebration is the formation of the vertebrae that gives a vertebrate its backbone.

Where does vertebration come from?
The word was formed in English from vertebra with the suffix -ation, a combination used to name a process. Its deeper roots lie in Latin vertebra, meaning a joint or vertebra, and ultimately in a Proto-Indo-European root associated with turning or bending. Related English words include vertebrate, vertebral, and vertebrated; they share the same Latin-derived base rather than being inflections of vertebration.

How vertebration is actually used
This is a rare, formal, and chiefly technical word used in anatomy, embryology, palaeontology, and comparative biology. It is more unusual when referring to the completed vertebral column, for which “backbone” or “vertebral column” is normally preferred.
Easily confused with vertebration
A vertebrate is an animal with a vertebral column, whereas vertebration is the formation of vertebrae or, more rarely, the resulting column collectively.
