mammary (English)

Where does "mammary" come from?

The English noun 'mammary' traces its lineage through the French word 'mammaire'[1][3], which was formed by combining the Latin root 'mamma', meaning 'breast'[1][2][3], with the suffix '-aire'[3]. The foundational Latin term 'mamma' itself has a debated origin, possibly arising as a childish onomatopoeic word or being borrowed from Ancient Greek 'μάμμη'[2].
