A large extinct relative of the elephant, with straight tusks and bumpy molars.

The Greek roots

μαστός
mastós
breast, nipple
+
ὀδούς
odoús
tooth

Literally: nipple tooth

The story of the word

Cuvier looked at the animal's molars, saw rows of rounded bumps, and called them breast-shaped. The name then spread from the teeth to the whole creature, so a several-tonne cousin of the elephant walks around under a word meaning nipple-tooth. The same μαστός sits inside mastectomy and mastitis.
