Sri Lankan Portuguese creole
Sri Lankan Indo-Portuguese, Ceylonese Portuguese Creole or Sri Lankan Portuguese Creole (SLPC) is a language spoken in Sri Lanka. While the predominant languages of the island are Sinhala and Tamil, the interaction of the Portuguese and the Sri Lankans led to the evolution of a new language, Sri Lanka Portuguese Creole (SLPC), which flourished as a lingua franca on the island for over 350 years (16th to mid-19th centuries).
