chlorineyoudaoicibaDictYouDict[chlorine 词源字典]
chlorine: [19] Chlorine is a greenish-yellow gas, and was named for its colour. The term was coined by the British chemist Sir Humphry Davy in 1810, from the Greek khlōrós ‘greenishyellow’. Of other words containing this element, chlorophyll [19] too was based on the notion of colour (in reference to the green colouring matter of leaves: the Greek elements literally mean ‘green leaf’), but chloroform [19], originally French, is a secondary formation based ultimately on chlorine (since it was originally regarded as a trichloride of formyl).

pictureyoudaoicibaDictYouDict
picture: [15] Picture and paint are very closely related. The Latin verb pingere ‘paint’ was the source of English paint, and its past participial stem pict- produced a noun, pictūra ‘painting’, which was eventually to become English picture. The same source produced English depict [17] and Pict [OE] (etymologically the ‘painted’ or ‘tattooed’ people), while its ultimate ancestor, the Indo-European base *pik-, *pig- ‘cut’, also evolved Latin pigmentum ‘colouring substance’, from which English got pigment [14] and, via Spanish, pimento [17].
