Koh, Seung-hui. 2017. “A Study on the Social Aspect through Neologism in Modern Polish”. The Sociolinguistic Journal of Korea 25(3). 29~64. The purpose of this paper is to research the word formation and meaning of newly coined words in modern Polish, and to investigate latest social changes in present Poland reflected in these new words. This paper consists of two main sections. The first section describes the linguistic analysis of newly coined words of Polish origin and loanwords from various languages. A large number of English words have flowed into Polish for a variety of reasons. English loanwords occupied about 70% of the database in this study database. The second section examines the socio-cultural changes through an analysis of words in various fields. From the analysis of gathered lexical database we can confirm the acceptance phenomenon of the most frequently, sometimes excessively used English loanwords among the young generation in Poland and look over the changes in Polish society through each word.
