The goal of this study is to find out the aspects of sociocultral dispositions and changes reflected on neologisms. To do this, two different sets of data are dealt with and investigated. The recent data are 2048 new words collected from 2012 to 2016 by National Institute of Korean Language; the older data are 2446 new words also collected by the same institute, which were published in 2007 in the book, Sajeone Eopneunmal Sinjoeo (Neologisms not found in a Dictionary). Since the former data were collected after smart phones were introduced and widely used, and the latter were collected before them, the comparison should cast some significant insights, especially because the principal source and the diffusing channel of new words are expected to be different. The data were divided by three broad categories, 『society』, 『life style』 and 『people』, which were further classified respectively into several relevant subordinate groups. The two sets of data were compared and examined based on their frequencies and characters. Some of the findings are as follows: interest in people and individual differences draw less attention than before; IT related words are detected in various sectors of the society, life style and people; leisure activities come to occupy a much more important role in people's lives; women draw more attention in terms of their roles and social recognition; the same is true with the elders; rather difficult times youngsters are going through seems to be reflected in many negative words related to them. It was also recognized that the recent data demonstrate more of the characterizations of younger generation's expressions and perspectives than those of older data, which reflects their more positive adaptations of digital conveniencies in public communication.
