补充资料:省声
      指汉字形声字的声符为某字的省略。省声的说法出于东汉许慎的《说文解字》。许慎分析文字结构, 凡形声字的声旁很明显的都注为"从某某声"。例如郊,"从邑交声";超,"从走召声"。但是有些字的声旁的笔画并不完备,许慎根据当时的字音推断某声旁是某一个字之省略,注出"从某某省声"。如:
  
  鬲部融,从鬲,蟲省声。
  
  生部産,从生,彦省声。
  
  夕部夜,从夕,亦省声。
  
  火部炭,从火,岸省声。
  
  火部炊,从火,吹省声。
  
  夭部奔,从夭,贲省声。
  
  疒部疫,从疒,役省声。
  
  鹿部麇,从鹿,囷省声。
  
  玉部琁,从玉,旋省声。
  
  这里有的字的声旁在小篆以前确实有不省略的写法,如旬从匀、夜从亦,都见于金文;産从彦,见于玺印;融从蟲、麇从囷为籀文,见于《说文》。不过大部分不见于秦以前的文字。许慎所推定为某字之省的也未必都对,如"奔"字金文从夭,下从歮,歮象人奔跑的足迹,是一个会意字。歮后来写为芔,《说文》 误以为是形声字,所以说"贲省声", 实际与古不合。虽然如此,其中大部分是有道理的。
