English was the official language of Sri Lanka during British colonization but it was replaced by Sinhala and Tamil as independence neared. The public sector was directly affected by this change although English held sway here for some years. Yet, English was made the link language for the Sinhalese and Tamils in 1987 and the state has since taken many steps to promote and improve its use in the public sector. Such change in language policy did not happen in void. It resulted from different perceptions nationalism and nationism had about English. This paper tries to understand the changing fate of English in Sri Lanka’s public sector by placing it in the context of nationalism and nationism. It aims to do two things, namely to explain nationalism and nationism in relation to Sri Lanka and to explore the presence of English in the public sector from independence until today, affected by nationalism and nationism. This investigative approach shows the influence of local ideology on language policy. It is ultimately seen that language policy concerning English in the public sector is responsive to the volatile political and social contexts of Sri Lanka.
