Word History

Etymology

borrowed from New Latin Paramecium, pre-Linnaean name for protozoa of the genus, from Greek paramḗkēs "oblong, oval" (from para- para- entry 1 + -mēkēs, adjective corresponding to mêkos "length, height, magnitude") + New Latin -ium -ium — more at meager

Note: The name Paramecium was introduced, in both Latin descriptions and English descriptions maintaining the Latin coinage Paramecium, by the English polymath John Hill (ca. 1714-1775) in An History of Animals (London, 1752, vol. 3 of his A General Natural History), p. 4. The word was first used as a Linnaean genus name by Otto Frederik Müller in Vermivm terrestrium et fluviatilium, seu, Animalium infusoriorum … succincta historia, vol. 1 (Copenhagen & Leipzig, 1773), p. 54 (spelled unetymologically Paramæcium, corrected in later publications).
