字谜是汉民族特有的一种语言文化现象,目前学术界少见有关字谜语法修辞方面的研究。字谜谜面中常常会出现不易被人察觉的语法偏离,产生语法单位变异、语法关系变异和语法层次变异等现象。这些变异现象虽然不合语法规则,却能产生含蓄委婉、简洁有趣的修辞效果。 Crossword is a kind of linguistic and cultural phenomenon unique to the Han nationality. At present, there are few researches in the rhetoric of grammar of grammar in academic circles. There are often imperceptible grammatical deviations in the riddle, resulting in phenomena such as grammatical unit variation, grammatical relationship variation and grammatical level variation. Although these variations are incompatible with grammatical rules, they can produce concise euphemism and concise and interesting rhetorical effects.
