Finished the tree
With only eleven lessons, the Navajo course is definitely in very early beta. Requires downloading a third party keyboard and there is still no audio. Lessons are very focused on nouns with only a hint of the rich complexity of Navajo verbs. Developers promise more soon. Still, this is a good start and a good refresher of my Navajo studied many years ago at San Juan College in Farmington. Is Navajo Made Easier still in print?
