Pronunciation

  • IPA: /ˈplæŋ(k).tən/[1]

Etymology

It is borrowed from German Plankton,[2][3][4][5][6] coined in 1887 by the German physiologist Viktor Hensen[4] from Ancient Greek πλαγκτόν (planktón), neuter of planktós “wandering, drifting”,[2][3][4][5][6] from plázesthai “to wander, drift”.[3][4][5][6] Merriam-Webster relates it to Latin plangere “to strike”.[5]

Earliest recorded meaning

All the floating or drifting organic life found at various depths in the sea or in fresh water (1891).[7][3][4][5]

Semantic evolution

The meaning has stayed close to Hensen's coinage.[7][4] The adjective planktonic is recorded in the AHD and Merriam-Webster,[2][5] and Wiktionary also uses the word for a single drifting organism, more often called a plankter.[1]
