slush [slush 词源字典]: slush: [17] Like the very similar (and perhaps ultimately identical) slosh [19] and sludge [17], slush probably originated in imitation of the sound of squelching or splashing. The similarity of early modern Danish slus ‘sleet, mud’ and Norwegian slusk ‘slushy’ suggests the possibility of a Scandinavian borrowing rather than a native formation. Slush fund [19] comes from the use of slush for ‘grease that is a byproduct of cooking in a ship’s galley’, the allusion being to the ‘greasing’ of people’s palms with money.
[slush etymology, slush origin, 英语词源]
by-product (n.): also byproduct; 1857, from by + product.
phene: as an element in names of chemicals derived from benzene, from French phène, proposed 1836 by French scientist Auguste Laurent as an alternative name for "benzene" because it had been found in coal tar, a byproduct of the manufacture of "illuminating gas," from Greek phainein "to bring to light" (see phantasm). Related: Phenyl (radical which forms the basis of derivatives of benzene); pheno- (comb. form).
