pezón
/peˈθon/ · B2 · noun · m
nipple
pezón = pez (fish) + ón: a little 'peck' point; sounds like 'pet-zone'
Sounds like 'pet-zone' with a lisped th: peh-THON. Linking it to Spanish pezón, from Latin pecciolus, a little stalk or foot, so it names a small stalk-like projection. The same root gives English petiole, a leaf stalk.
