From Proto-Athabaskan *x̣aɣʸ (“winter”).
In Navajo, the initial fricative *x̣ of Proto-Athabaskan didn't sonorize to gh, so in verbal stems and in the nominal stem hai (“winter”) the initial voiceless fricative h is maintained (with the exception of the adverbial derivative díí ghaaí or dííghaaí (“this winter”), which shows a later sonorization). See also -ZHĮ́ (“summer”) for a similar situation.
