Cojones

Cojones (s. cojón ) and huevos (eggs) or bolas/pelotas (balls) are vulgar Spanish curse-word usages for testicles. The singular form, cojón contains the augmentative suffix -ón (implying magnitude), and derives from the Vulgar Latin coleonem, the accusative form of coleo (testicle), an augmentative form of cōleus (leather bag for liquids); its variants are cūleus and culleus. The le → j or li → j pronunciation shift is common to Latin and Spanish, e.g. folia → hoja (leaf), which is a cognate with the English word "foliage".
