n

Etymology
the word "kelp" first appeared in late middle english, but its ultimate origin is obscure. it is likely related to, or a borrowing from, middle dutch or a similar low german source, where it referred to the ash produced by burning seaweed, which was used in making soap and glass. over time, the meaning shifted from the processed ash to refer directly to the large brown seaweeds themselves, particularly those of the order laminariales. this transition reflects the word's journey from a specific industrial product to a common biological term for the living plant.
