More about peduncle
The English noun peduncle is a technical term in the biological sciences, meaning “a stalk, flower stalk, stem.” Peduncle comes from New Latin pedunculus, with the same meanings, a derivative of Latin pēs (inflectional stem ped-) “foot” and the suffix –unculus, a variant of –culus, used to form diminutives. Latin pēs, ped– comes from the very widespread Proto-Indo-European root ped-, pod-, pēd-, pōd “foot.” The variant pōd– regularly becomes fōt– in Proto-Germanic, fōtus in Gothic, fōtr in Old Icelandic, fōt in Old English, and foot in English. The variant pod– becomes pous (stem pod-) “foot” in Greek, and the preposition pod “under” in Slavic. The Latin suffix –unculus is uncommon, but it also appears in Latin homunculus “human being, mere human being (as opposed to preternatural or supernatural beings or forces),” English homunculus. Peduncle entered English in the early 18th century.
