As digital technology becomes more prevalent in today’s business environment and interest in digital trust rises, restaurants need to identify whether and how their mobile apps enhance the customer experience, and what features of the apps can strengthen customers’ attachment to them. However, few studies have examined the role of restaurant mobile apps as a catalyst for building customer loyalty. Considering restaurant mobile apps as a means to build a trustworthy relationship between customers and restaurants, this study develops and validates a research framework to measure digital trust between restaurants and customers through restaurant mobile apps. Specifically, due to the lack of measurement constructs for digital trust, a reliable and valid set of measurements that can explain digital trust in relation to restaurant mobile apps is developed and the effects of mobile apps’ digital trust on customers’ trust in a restaurant brand, overall experience, and their continued use intention are assessed.

Crosslinguistically, basic motion verbs similar to the English go and come have been shown to be highly susceptible to grammaticalization. However, there has been relatively little emphasis in previous research on the grammaticalization of the English motion verb come. This paper attempts to redress some of the balance by investigating the grammaticalization of come, with particular emphasis on its occurrence in Serial Verb Constructions. The major aim is to provide a detailed account of how the semantic change undergone by come in such contexts is effected by a number of diverse mechanisms, including metaphor, metonymy and subjectification. In addition, certain functional properties of the grammaticalized come will be discussed, along with certain morphosyntactic changes that occur by way of reanalysis. The result of this analysis should demonstrate that come in its serialized form has undergone extensive grammaticalization, shifting from a fully lexical verb to a functional item in its semantic, categorial and morphosyntactic aspects.
