plankton: [19] The ultimate source of plankton is Greek plázein ‘hit’, a descendant of the same base as produced English apoplexy, plague, and plectrum. The link between these two unlikelysounding relatives is that something that is hit moves or wanders, and plankton are minute organisms that wander or drift in the ocean. The Greek derivative plagtón meant ‘wanderer’, and the application to ‘plankton’ was first made in German in the 1880s. => plague
