Actually, Genuinely, Really, and Truly

Using the 400+ million-word Corpus of Contemporary American English (COCA) as data and a behavioral profile analysis approach, this study examines the semantic and usage differences among actually, genuinely, really, and truly, four near-synonymous adverbs notorious for their complex functional and syntactic usage patterns. In addition to examining the collocates of the adverbs (i.e. the common types of adjectives/verbs they each modify), the study also investigated the positions the adverbs typically occupy in the sentence structure and their functional implications. The data analysis yields an informative delineation of the internal semantic structure of the synonym set, which includes some interesting new findings compared with existing descriptions of the adverbs. The results also show the need for the BP approach to go beyond collocational analysis in the study of synonymous adverbs. Finally, the study also demonstrates the viability of a corpus-based BP approach in the study of synonymous adverbs.
