Etymology: "Phycophyte" is a compound of two Greek elements. "Phyco-" comes from "phykos," which meant seaweed, and "-phyte" comes from "phyton," meaning plant, from the verb "phyein," to grow. Put together, they give something like "seaweed-plant," a label for the water-dwelling organisms that photosynthesize. The term is a plain scientific formation rather than a word with a colourful history. Botanists assembled familiar classical elements to name a category of organisms. The first element also appears in "phycology," the study of algae, so the two terms share a root. The first part of the compound points to seaweed, but the category it names is broader and covers algae of many kinds.
