μαστός

Ancient Greek

Perhaps related to μαδάω (madáō, “to be moist”). If so, then from Proto-Indo-European *meh₂d- (“wet, glossy, fat, well-fed”).

μᾰστός • (măstós) m (genitive μᾰστοῦ); second declension

(anatomy) a breast (organ containing mammary glands)
1. (especially of women) a human breast
2. (zootomy, rare) udder
(figurative) any round, breast-shaped object:
1. a round hill
2. a round piece of wool fastened to the edge of nets
3. (Pamphylian) a breast-shaped cup

All usage contradicts the statement of the Grammarians that μαζός (mazós) is the man's breast, μαστός (mastós) the woman's.

Second declension of ὁ μᾰστός; τοῦ μᾰστοῦ (Attic)
