      英文詞源


      paraffin
      paraffin: [19] The term paraffin was coined in German around 1830 by the chemist Reichenbach. It was formed from Latin parum ‘little’ and affinis ‘related’ (source of English affinity), an allusion to the fact that paraffin is not closely related chemically to any other substance. The word is first recorded in English in 1838.
      => affinity, fine
      paraffin (n.)
      1838, from German Paraffin, coined c. 1830 by German chemist Karl von Reichenbach (1788-1869), who first obtained it as a waxy substance from wood tar, irregularly from Latin parum "not very, too little," probably related to parvus "little, small" (see parvi-) + affinis "associated with" (see affinity).

      So called because paraffin is chemically not closely related to other substances. The liquid form (originally parafin oil) Reichenbach called eupion, but this was the standard meaning of paraffin in English by 1860.
