從形成上説,BA式雙音狀態形容詞的意義基礎是比擬,結構基礎是各類以單音性質形容詞爲核心的偏正結構。從演變上説,BA式雙音狀態形容詞語義上表狀態、表程度的功能有不斷弱化和主觀化的趨勢;結構上有由雙音節向多音節發展的趨勢,最後主要向BABA式重叠發展;語音上,B語素通過延長讀音和改變讀音的方式來增强自己的生動性和表現力。 In terms of formation, the basis of the BA type dual-tone state adjectives is comparatively based on the structure of various types of monophonic structures centered on adjectives with monophonic properties. In terms of evolution, the function of semantic table status and table degree of the adjectives with double diatonic states of BA are continuously weakened and subjectivized. The structure tends to develop from syllable to syllables and finally to overlap with BABA. Phonetically, B morpheme enhances its vivacity and expressiveness by prolonging its pronunciation and changing its pronunciation.
