enjoyyoudaoicibaDictYouDict[enjoy 词源字典]
enjoy: [14] Originally, enjoy was used intransitively in English, rather as in the modern American Yiddish-influenced injunction ‘Enjoy!’: ‘Yet he never enjoyed after, but in conclusion pitifully wasted his painful life’, Robert Laneham 1549. However, by the end of the 16th century the transitive sense ‘take pleasure in’ had virtually taken over the field. The word probably comes from Old French enjoïr, a compound formed from the prefix en- ‘in’ and joir ‘rejoice’, which in turn came from Latin gaudēre (ultimate source of English joy).

Old French did have another, similar verb, however, enjoier (formed from the noun joie), which probably also played a part in the English acquisition.

kindergarten (n.)youdaoicibaDictYouDict
1852, from German, literally "children's garden," from Kinder "children" (plural of Kind "child;" see kin (n.)) + Garten "garden" (see yard (n.1)). Coined 1840 by German educator Friedrich Fröbel (1782-1852) in reference to his method of developing intelligence in young children.
Kindergarten means a garden of children, and Froebel, the inventor of it, or rather, as he would prefer to express it, the discoverer of the method of Nature, meant to symbolize by the name the spirit and plan of treatment. How does the gardener treat his plants? He studies their individual natures, and puts them into such circumstances of soil and atmosphere as enable them to grow, flower, and bring forth fruit,-- also to renew their manifestation year after year. [Mann, Horace, and Elizabeth P. Peabody, "Moral Culture of Infancy and Kindergarten Guide," Boston, 1863]
The first one in England was established 1850 by Johannes Ronge, German Catholic priest; in America, 1868, by Elizabeth Peabody of Boston, Mass. Taken into English untranslated, whereas other nations that borrowed the institution nativized the name (Danish börnehave, Modern Hebrew gan yeladim, literally "garden of children"). Sometimes partially anglicized as kindergarden (attested by 1879).
