Abstract

The purpose of the current study is to clarify the trend of the new suffix -mi of emotional and sensory adjectives on Twitter from 2006 to 2019. The study examined both the number and the trend of tweets from 2006 to 2019 by targeting the new suffix -mi of 53 emotional and sensory adjectives. It used Twitter since the new suffix –mi has been is appearing on Twitter, and all tweets on a specific date can be found if you specify a date. First, it was established that the frequencies of token and type of the new suffix -mi in tweets have been increasing year by year. Second, by comparing the new and the original suffix -mi, it was discovered that the frequencies of token of original suffix –mi (8 words) had far higher growth rates than those of the new suffix –mi (53 words). In the case of the type of frequency, while all of the original suffix -mi have appeared since 2008, the new suffix -mi first appeared over time from 2007 to 2016, and some new suffix -mi no longer appeared. Third, it also showed that the token frequency of the new suffix -mi in tweets has been increasing compared to the increase of Twitter users in Japan over the past four years from 2015 to 2018. In addition, in the token study of each new suffix –mi, when comparing 2019 to the year that the suffix first appeared, it seems that the earlier the new suffix appeared, the higher its growth rate was. Also, the new suffix -mi of emotional and sensory adjectives that express the subject's emotions tends to have higher growth rates.
