Origin: A borrowing from Latin, combined with an English element; modelled on a German lexical item. Etymons: Latin parellus , -ic suffix.

Etymology: < scientific Latin parellus (see perelle n.) + -ic suffix, after German Parellsäure (E. Schunck 1845, in Ann. der Chem. u. Pharm. 54 258).

Chemistry.

parellic acid n. a crystalline acid, C₁₈H₁₄O₈, which is a depsidone obtained from various lichens, esp. Ochrolechia parella.
