† margaritic acidn.

Origin: A borrowing from Latin, combined with English elements; modelled on a French lexical item. Etymons: Latin margarīta , -ic suffix, acid n.

Etymology: < classical Latin margarīta margarite n.¹ + -ic suffix + acid n., after French acide margaritique (A. Bussy & L.-R. Lecanu 1827, in Jrnl. de pharm. 13 76). N.E.D. (1905) enters this under margaritic and gives the pronunciation as (māɹgări·tik) /mɑːɡəˈrɪtɪk/.

Chemistry. Obsolete.

Any of several fatty acids; spec. (a) the margaric acid of Chevreul (see margaric adj. 1a); (b) (in quot. 1839) a fatty acid resulting from the saponification of castor oil.The formula given in quot. 1851 corresponds in modern notation to C₁₁H₂₂O₂ (undecanoic acid), which does not occur in natural fats.
