Baybayanon was originally a Warayan language that has been relexified and overlaid by a Cebuano (Leyteño) superstratum.[2] The Warayan substratum is characterized by Baybayanon's more Waray-like deictics, and various other features.[2]
Utudnon is spoken by about 10,000 people in five barangays of Baybay municipality,[3] central Leyte, namely Utúd (also called Utod or Guadalupe), Gábas, Kilím, Pátag, Pangasúgan and Hibunawan.[2]
