psyllium
UK[ˈsɪlɪəm]US[ˈsɪlɪəm]
n
A plant of the genus Plantago, whose seeds are used as a laxative and dietary fiber supplement.
Etymology
The word "psyllium" entered English via Latin from the Greek word "psyllion," which referred to the fleawort plant. The Greek term itself is a diminutive of "psylla," meaning "flea," likely due to the small, flea-like size and appearance of the plant's seeds. This etymological journey illustrates a classic descriptive naming pattern, where a physical characteristic (resemblance to a flea) of a natural object (the seed) becomes the basis for its scientific and common name.
Analysis
The entire word "psyllium" is a simplex loanword from Greek. It does not contain separable, meaningful morphemes in modern English spelling.
Examples
