Etymology
the word 'inulin' is a modern chemical term derived from the new latin genus name 'inula', which refers to a group of plants including elecampane. the latin plant name 'inula' itself is of obscure, possibly non-indo-european, origin. the suffix '-in' is a standard chemical suffix adopted from latin, used to denote substances. thus, the term literally means "a substance derived from or found in the inula plant," directly linking the botanical source to the polysaccharide first isolated from its roots.
