the word 'sunchoke' is a modern marketing name coined in the 1960s to rebrand the jerusalem artichoke, a plant whose tubers are its edible part. the name is a compound of 'sun', referring to the plant's membership in the sunflower family (helianthus), and 'choke', a phonetic play on the italian word for sunflower, 'girasole'. this was likely an attempt to avoid the confusing and misleading 'jerusalem' part of its older name. thus, the literal morphemes combine to create a name that logically links the plant to its sunny origins while utilizing a familiar, if semantically disconnected, english word for phonetic appeal.

Structure: sun (sun) + choke (choke) - sun: from old english sunne, of germanic origin; related to dutch zon and german sonne, from an indo-european root shared by greek hēlios. functions as a noun, referencing the celestial body. - choke: from middle english choken (to suffocate), a shortening of old english āċēocian (to suffocate). functions as a verb, but here used in a compound noun.
