The areas of Central America that formed part of Mesoamerica during the preclassic were inhabited by Lenca and Jicaquean speakers. Based on placenames, it appears that Xincan languages were originally spoken in western El Salvador, but were replaced by Nawat after postclassic migrations. The migrations of Subtiaba and Mangue speakers, possibly also during the postclassic period, expanded the realm of Mesoamerican cultural influence to include the Pacific coast of Nicaragua and the Nicoya Peninsula, which were previously part of the Isthmo-Colombian area and probably inhabited by Misumalpan and Chibchan speakers.
