planktonic

The word 'planktonic' is built upon the core concept of drifting. Its ultimate source is the Greek verb plazesthai, meaning 'to wander' or 'to drift', which gave rise to the adjective planktos ('drifting'). This adjective was nominalized with the suffix -on to create plankton, the collective term for the passively floating organisms in water. The English adjectival suffix -ic was then appended, directly converting the noun into an adjective describing anything pertaining to or characteristic of this drifting life. Thus, the term's logic moves from the ancient action of wandering to a specific modern ecological category and finally to the descriptive quality of belonging to it.
