launchyoudaoicibaDictYouDict[launch 词源字典]
launch: English has two separate words launch. The verb, ‘propel’ [14], is related to lance. Lances are propelled by throwing, and so the derived Old French verb lancier was used for ‘throw’. English acquired it via the Anglo- Norman form launcher. The sense ‘put a boat into the water’ emerged at the end of the 14th century. From the same source came modern French élancer ‘throw out’, whose derivative élan was acquired by English in the 19th century. Launch ‘boat’ [17] comes via Portuguese lancha from a Malay word related to lancharan ‘boat’.

SacagaweayoudaoicibaDictYouDict
also Sacajawea, name of the Shoshoni woman who accompanied the Lewis & Clark expedition.
She had been a captive among the Hidatsas (a Siouan people), and her Hidatsa name was tsaka'aka wi'a, lit. 'bird woman' (Hartley, 2002). Her Shoshoni name, rendered as Sacajawea and translated 'boat launcher,' may have been a folk-etymological transformation of the Hidatsa term (Shaul, 1972). [Bright]
Her image appeared on U.S. dollar coins from 2000.
