Morphology

innominata = innominate (opaque) = in + nomin + a

Formally derived from 'innominate' with a Latin noun ending, but the historical/archaic application to the brachiocephalic artery is a specialized usage.

Etymology

Innominata comes from the Latin parts in- 'not' and nomen 'name', so it literally means 'unnamed'. Older medical books used innominata for the large artery from the heart now usually called the brachiocephalic artery.
