Stem set

 * 1) In the perfective, ∅-classifier themes always take a d-classifier:
 * d + -yaa = -dzaa
 * 1) ł-classifier and stem-initial merge as follows:
 * ł + -nééh = -∅-lééh
 * ł + -yaa = -∅-laa
 * 1) Under d-effect for 1st person duoplural and passives, classifier merges first:
 * (d + ł) + -nééh = -l-nééh
 * (d + ł) + -yaa = -l-yaa
 * 1) Under d-effect for ná-reversionary, stem initial merges first:
 * d + (ł + -nééh) = -d-lééh
 * d + (ł + -yaa) = -d-laa
