Although little is known about the language of the ancient Astures, it may have been related to two Indo-European languages: Celtic and Lusitanian. Words from this language and the pre–Indo-European languages spoken in the region are known as the prelatinian substratum; examples include "bedul, boroña, brincar, bruxa, cándanu, cantu, carrascu, comba, cuetu, güelga, llamuerga, llastra, llócara, matu, peñera, riega, tapín" and "zucar". Many Celtic words (such as "bragues, camisa, carru, cerveza" and "sayu") were integrated into Latin and, later, into Asturian.
