The Flores–Lembata languages are a group of related Austronesian languages (geographically Central–Eastern Malayo-Polynesian languages) spoken in the Lesser Sundas, on eastern Flores and small islands immediately east of Flores. They are suspected of having a non-Austronesian substratum, with extreme morphological simplification in Sika and secondarily in Alorese, but not to a greater extent than the Central Malayo-Polynesian languages in general.
