mar

IPA: [mar]
n. blood. The red fluid that flows through the human veins.

A pretty simple word today. Its use is mainly in medicine, but some ancient Tulvan poetry hints to a very dark past and usage for this most sacred fluid. Some other derivates may also include utimmar meaning 'sap', although this is a more "poetical" resource for naming it.

Example: Cur goiven umar crumen gim.
The gods desire the blood of men.
(From a very ancient codex)
