Diachronic Changes of Frequencies in Discourse Connectives in English: Evidence from COHA

Recent studies have claimed that the amount of discourse connectives or discourse markers has risen in multiple languages. However, the thesis has seldom been evaluated using comprehensive empirical data evidence. This study investigates the historical changes of frequencies in discourse connectives in the English language over the last two hundred years. We find that the frequencies of the majority of discourse connectives showed a marked decrease. An opposing trend can be seen with respect to only a few types of discourse connectives. These research results show that the frequencies of discourse markers in English have not in fact increased over the last two centuries. We analyze the possible reasons for this decline. And this result suggests that English language users tend to use explicit discourse connectives less frequently, which finding may challenge recent claims concerning the rise of discourse connectives (markers).
