Tourism discourse as a domain-specific discourse is characterized by a set of linguistic, pragmatic, and function features that make it different from other discourses and the general language. One of its essential elements is the usage of appealing, innovative, exotic-sounding words in order to attract potential tourists by "persuading, luring, wooing and seducing" [6]. In this context, formulaic language plays a key role. To date, research into chunks of language used in tourism have mostly focused on collocations [1,8,23], with a few works on longer sequences [11,12,13]. Bearing this in mind, this paper aims to contribute to the analysis of 4-word bundles in this domain, more specifically, in the segment of adventure tourism. To do so, a corpus-driven analysis was undertaken. As for our methodology, a specialized corpus containing English promotional texts was compiled. After that, the software Sketch Engine was used to extract a list of potential 4-word bundles. Next, manual verification was performed to ensure the validity of the units. Finally, the resulting list was classified according to their structural framework and their function in the text. The findings show that, in terms of the structure, the most typical sequences were verbal bundles; on the other hand, in terms of the function, a significant amount of the units was mainly used to address readers directly.
