the word 'zinnia' entered english in the 18th century as a direct adoption of the modern latin genus name. this name was coined by the swedish botanist carl linnaeus in honor of johann gottfried zinn, a german professor of botany and anatomy who provided some of the earliest detailed descriptions of the plant. unlike many scientific terms built from greek or latin roots, 'zinnia' is an eponym, a word derived from a person's name. its journey reflects the scientific practice of naming new world flora after european scholars, with the word's form remaining unchanged as it transitioned from a taxonomic label into common gardening vocabulary.

the word is a modern latin genus name, derived from the surname of the german botanist johann gottfried zinn. it does not contain segmentable classical morphemes in the english spelling.
