This study aims at clarifying aspects of use of suffixes and grasping the coinage ability in terms of productivity in sixth grade children after extracting derivatives using suffixes from the origin Korean appeared in their diary corpus. Since 6th grade, the development of formal operation starts. Their diary corpus, therefore, are good at identifying their vocabulary ability manifesting their thought with glossary. With the reason, this study trys to extract derivatives using suffixes from the origin Korean appeared in the diary corpus of 6th grade with analysis of meta-quantitative research. This article formulates the “Using productivity" to “GP=n1(T)/)N(only if N≧2)" after existing methods of measuring productivity by examining the advantages and disadvantages of them. The result of assignment to the formula is that the order of productivity of suffixs is “-meori, -thusʌŋi >-ki > -tuŋi > -k'urʌki > -k'un > -kæ> -tsæŋi > -tsil > -s'i > -i > -(ɨ)m > -po, -i1, -tsaŋi, -tsiki, -ts'ak, -putshi, -ts'ɨki, -atshi”. I analyze use patterns of derivatives of the sixth grade students in elementary school based on these statistic results. The result is, the firstly, that the suffix of the index number of 1 are “-meori, -thusʌŋi". There are comparatively many hapax legomena compared with the total tokens. The second is that the large tokens ones among suffixes are “-ki, -kæ. -i, -(ɨ)m". These occupied most amount to 93% among the total sum of tokens of suffixes. The “-(ɨ)m” among four are the lowest productivity. The reason is that the body of combination of -(ɨ)m with V(verb) become base, and then, the base generates the structure of compound word while the suffix of ‘-ki' occupied to high rank exponent of productivity make the structure of derivative word. The third, there are many temporal derivatives using suffix “-ki, -kæ" appeared in syntactic environment in which the category of the combination become temporally derivatives one. The fourth, the features of the components of hapax legomena of derivatives included in ‘-i' is that there are many dependant bases and the forms such as k'ɔtsi, s'ɨri, kʌri, matsi'. The standard form of sætshimduŋi is sætshimt'ki but the latter form appeared in their diary corpus as the new coinage. The sixth is that ‘-k'urʌki, -k'un, -tsæŋi' occupy high rank position, that reason is also that there are comparatively many hapax legomena compared with the total tokens below average. The seventh is the productivity of index of ‘-tsaŋi, '-tsiki, -atshi, -ts'ɨki, -putshi' is zero. The reason is that the productivity is related with diachrone, low frequency, and the limitation of size of diary corpus. The ninth is the index of productivity of ‘-sæ, -sari, -pæŋi, -k'al have no meaningless because there is no comparing words with them.
