n
A type of plant with thick fleshy leaves, often with yellow, white, or pink flowers, that grows on walls or rocks.
Etymology
The word 'sedum' entered English directly from Latin, where it served as the name for a houseleek plant. The Latin term is believed to have originated from the verb 'sedare', meaning 'to settle' or 'to calm', likely in reference to the plant's traditional use in soothing inflammations. This botanical name was adopted into scientific and later common usage to classify a broad genus of succulent plants. Thus, the modern term retains its classical name, carrying a history of herbal application within its simple form.
Analysis
The word is a simplex loanword from Latin. It does not contain separable, meaningful morphemes within its modern English spelling.
