The Carrier syllabary, or Déné Syllabics, was devised by Father Adrien-Gabriel Morice in 1885. He adapted it from the syllabic writing systems developed for the Athabaskan languages of the Northwest Territories of Canada by Father Emile Petitot.
The Carrier syllabary was fairly widely used for several decades for such purposes as writing diaries and letters and leaving messages on trees. Though the syllabary is no longer used or understood by many people, there has been a recent revival of interest in it and it occasionally appears on plaques and memorials.
In the 1960s, the Carrier Linguistic Committee in Fort St James developed an alternative writing system based on the Latin alphabet. This system is now the most popular writing system for Dakelh.
