Vertebroiliac is a medical term that is used to describe the ligaments that connect the ilium to the vertebrae. The spelling of this word is quite complex, as it is made up of several different roots and suffixes. The first part of the word, "vertebro-", comes from the Latin word "vertebra", which means spinal column. The second part, "-iliac", refers to the ilium bone. The correct pronunciation of this word is /ˌvɜːtəbrəʊˈɪliæk/.
Relating to the vertebrae and the ilium, iliolumbar; noting a ligament.
