Lee Jin-sung. 2013. Writing Practice of English Chatting Language and its Different Communication Strategies from That of Korean. The Sociolinguistic Journal of Korea 21(3). The purpose of this study is to introduce writing practice of English chatting language, especially focusing on that of text messages. It also discusses different communication strategies of English chatting language from that of Korean. The two characteristic features of text message writing are presented as a violation of conventional writing practice and various manners of shorthand writings. As for shorthand writings, initialisms, vowel omission, clippings, ideograms, pictograms, and phonetic spellings are dealt, together with their functional perspectives. The communication strategies of English chatting language were found to be reflected only on various shorthand writing practice which depicts the degree of formality but manifests lack of articulating detailed emotion or conversational keys. The communication strategies of Korean chatting language, on the other hand, were found to be able to demonstrate various conversational keys with the help of novel inflectional mutation, shortening, syllable extension, consonant addition or with adoption of regional dialects. While English chatting language is associated with positive influence on literacy, vocabulary, and phonological awareness among children as well as adults, Korean chatting language seems to have somewhat negative influence on standard written language and orthography.
