Word origin
[1860–65; iso- + Gk ster(eós) solid, hard + -ic]This word is first recorded in the period 1860–65. Other words that entered Englishat around the same time include: big brother, institutionalism, jumping jack, metric system, monismiso- is a combining form meaning “equal,” used in the formation of compound words (isochromatic). In chemistry, iso- is used in the names of substances which are isomeric with the substance denotedby the base word (isocyanic acid). Other words that use the affix iso- include: isodiametric, isodynamic, isomorphous, isostasy, isotope; -ic is a suffix forming adjectives from other parts of speech, occurring originally inGreek and Latin loanwords (metallic; poetic; archaic; public) and, on this model, used as an adjective-forming suffix with the particular senses“having some characteristics of” (opposed to the simple attributive use of the basenoun) (balletic; sophomoric); “in the style of” (Byronic; Miltonic); “pertaining to a family of peoples or languages” (Finnic; Semitic; Turkic)
