aprotic in American English
(eiˈproutɪk)
adjective
Chemistry
not containing dissociable hydrogen
Word origin
[a-6 + prot(on) + -ic]-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)
