quinaquinan.

Etymology: Apparently < Spanish quinaquina (see note) and its apparent etymon Quechua kina-kina, reduplication of kina bark (see quina n.), in early use probably via post-classical Latin china-china cinchona bark, cinchona tree (1681 or earlier; also quinaquina (1713 in the passage translated in quot. 1715 at sense 1)), French quinaquina cinchona bark (1653), cinchona tree (1716; also as †china china (1703)), or Italian chinachina (a1698). With sense 1 compare earlier quina n., quinquina n.The early semantic history of Spanish quinaquina is complex. It is apparently first attested in 1569, and subsequently in a group of texts dating from the beginning of the 17th cent., denoting an aromatic tree whose timber is used in construction, and whose resin and seeds have numerous medicinal uses (among which, however, use as a fever remedy is not mentioned); it is likely that this tree is identical with Myroxylon balsamum (compare quinoquino denoting the tree from which balsam of Peru is obtained (1792 or earlier)), and that Quechua kina-kina originally denoted the same tree. Subsequently (perhaps as a result of confusion with Spanish quina quina n.) Spanish quinaquina was transferred to the cinchona tree (and its bark), in which senses it is first recorded in the Academy Dictionary of 1737, although the earlier attestation of these senses in both French and post-classical Latin suggests earlier currency in Spanish as well (compare also discussion of quot. 1656 at quinquina n.). Spanish quinaquina then seems to have been reborrowed into its donor language in the senses ‘Cinchona bark’ and ‘Cinchona tree’. See further R. Loewe 1932, in Zeitschr. f. vergl. Sprachforschung 60 153–62. With the reduplication in Quechua compare:1880 C. R. Markham Peruvian Bark 5 In Quichua, when the name of a plant is reduplicated, it almost invariably implies that it possesses some medicinal qualities.
