Study of this paper is mainly about three forms of two-syllable reduplication ; ABAB, AABB, bothABAB and AABB type.
In case of using ABAB reduplication form, it was examined to have been used in parallel structure, verb-object construction, verb-complement construction, and modifying construction.
The two-syllable verbs superimposed in ABAB form have a strong internal cohesion between the two letters, so that the relationship between the two letters is close. That is, it is hardened with one word and can not be used separately.
AABB reduplication form, it was examined to have been used in parallel structure. It had a meaning of repetition and continuity, and there were many cases of negative meaning.
The AABB formula found in the Modern Dictionary (7th edition) showed that the AABB formula has lexical features. Part-of-speech was converted after verb overlap, and AABB was considered to be suitable for descriptive function.
Some two-syllable verbs could be used in both ABAB and AABB expressions, and the positive ones of the bisyllable verbs could be placed in ABAB, and the negative cases in AABB.
