Although Singapore, a linguistically and ethnically diverse city-state, uses four official languages, namely Malay, Mandarin, Tamil, and English, which are supposed to enjoy equal status, there appears to be a pecking order to these languages. English seems to be the dominant language when taking into consideration the bilingual education policy, numerous campaigns promoting its use in terms of spoken language, and language use by the media. Another mechanism that also contributes to the predominance of English over the other three official languages is linguistic landscape, i.e. language use in public space. Adopting the ecology of language as its conceptual framework and linguistic landscape as its methodological tool, this article, by analyzing public signs in and around 30 MRT (Mass Rapid Transport) stations of the Circle Line (CCL), discloses not only English imperialism but also the complexity of this language in Singapore with its dual identity as a global language as well as a local one. Consequentially, it is postulated that Singapore is monolingual- rather than bilingual- or multilingual-oriented.
