Plural of cadera; the hips or hip region, a term used in anatomy and Spanish-influenced English.
From Spanish 'cadera,' derived from Latin 'cathedra' (chair). The hip was metaphorically called a 'chair' or seat where the body rests.
The Spanish word 'cadera' reveals how Latin vocabulary diverged—what became 'cathedral' (a chair as a seat of authority) became 'cadera' (the literal chair of the body).
