English in India evokes connotations of worldliness, education, class, and power. Although many less socially fortunate groups lack in the English language competence, its presence in the Indian street is increasing, and not only in the context of tourism and marketing. The investigation of the linguistic landscapes of a number of localities in northern India will focus on public service advertisements written in English which convey guidelines for the creation of a healthier Indian society. The study, informed by the rhetoric of social intervention approach, investigates the choice and the frequency of the persuasive rhetorical devices used in the texts. It also discusses which of the three modes of persuasion typically underlie the analysed advertisements, thereby highlighting the preferred approach to tackling local issues and, indirectly, contributing to strengthening the role of English through the positive perception of the messages conveyed.
