kaleidoscope[kaleidoscope 词源字典]

kaleidoscope: [19] Greek kalós meant ‘beautiful’ (it was related to Sanskrit kalyāna ‘beautiful’). It has given English a number of compound words: calligraphy [17], for instance, etymologically ‘beautiful writing’, callipygian [18], ‘having beautiful buttocks’, and callisthenics [19], literally ‘beauty and strength’. The Scottish physicist Sir David Brewster used it, along with Greek eidos ‘shape’ and the element -scope denoting ‘observation instrument’, to name a device he invented in 1817 for looking at rotating patterns of coloured glass – a ‘beautiful-shape viewer’.
