Etymology: "Pondweeds" is the plural of "pondweed", a compound built from two plain English words: "pond" and "weed". Each part keeps its ordinary sense. A pond is a small body of standing fresh water, and "weed" in its older, broader sense meant any plant growing where it was not wanted or was not cultivated. Joined together, the name describes exactly what it names: plants that grow in ponds. The compound is a transparent piece of English word-building rather than a borrowing, so there is no foreign root to trace. The plural simply adds the usual "-s" to the end of "pondweed" and refers to the whole group of such plants, which botanists divide into several families, many of them in the genus "Potamogeton".

Synonyms: aquatic plants, macrophytes, waterweeds, submerged plants, hydrophytes
