诗歌中曲子格律规定之外增加的字叫衬字,是和正字相对而言的。就形式而言,衬字好像是多余的字,就内容讲却不是可有可无的字,而是按格律不算字数,吟唱时可以不占音节,意思却与全句形成补充作用的字。衬字在词曲和配乐作品中常见,在近体诗中则绝对没有。 In poetry, the addition of the rules of music rules is called lining, which is relative to orthography. In terms of form, the lining of the word seems to be redundant words, content is not insignificant words, but according to the law is not the word, singing can not account for the syllable, but the meaning of the whole sentence to form a complementary role of the word . The lining word is common in songwriting and soundtrack works, but not in near-body poetry.
