“罔A罔B”和“来A来B”是莆仙话的高频框式结构,表示B随A的变化而变化,但二者同中有异。它们分别是权且义副词“罔”与趋向动词“来”框式化的结果。演化的成因有三——相近的语义基础触发相近的演变,共同语“越A越B”的类化作用,邻近的闽东福州话的渗透与影响。“罔”的权且义和倚变义是闽语的重要特征,其语义演化过程为“权且义>并列义>倚变义”。 “A indiscriminately A indiscriminately B ” and “to A to B ” is the high-frequency box structure of Pu Xian dialect, that B changes with the changes of A, but both with the same. They are the result of the formalization of the right and the righteous adverb “” and the trend verb “to ”. There are three causes of evolution: the similar semantic base triggers the similar evolution, the common language “the more the more the B ”, the infiltration and influence of the neighboring Fuzhou dialect. “Unrequited ” right and righteousness and deference is an important feature of Min Dialect, its semantic evolution process “right and righteousness> paraphrase> reliance on righteousness ”.
