Morphology

brown + algae

The meaning 'a group of algae that are brownish in color' is directly and transparently derived from combining 'brown' (a colour adjective) with 'algae' (plant-like organisms). This adjective‑noun descriptive pattern is a basic, cross‑linguistic composition that a B1 learner who knows both words would readily understand.

Etymology

Brown algae comes from a simple picture: the word brown describes the brown and yellow colors that hide the green, and algae means plants in the sea. So, brown algae is the name for large 'seaweeds' such as kelp that look 'brownish' or 'olive' today.
