The Comparative Method and Language Reconstruction 1. Find sound correspondences. When there is no divergence, reconstruct for the parent language the same sound as is found in the daughter languages. Where there is divergence reconstruct one sound for the parent language. Describe the sound changes that occurred in each of the daughter languages.
Consonants become voiceless at the ends of words.
Vowels become nasal before nasal consonants and the nasal consonants then drop. Sounds are more likeley to be deleted than inserted. There is no divergence.
