plankton (English)

Where does "plankton" come from?

The English noun 'plankton' was borrowed from German 'Plankton', which was coined in 1887 by the German zoologist and marine biologist Victor Hensen[1][2]. The German term is ultimately derived from the Ancient Greek neuter nominative 'planktón', meaning 'drifting', which comes from 'planktós' meaning 'drifter'[1][2]. This Greek form traces back to the verb 'plázō', meaning 'to cause to wander, drive astray' or 'I turn aside, wander'[1][2].

Open questions

• The derivation of the Ancient Greek verb 'plázō' from a Proto-Indo-European root meaning 'to strike' is problematic due to divergent semantics, leading some scholars to favor a Pre-Greek origin. [4]
