VERB STEMS.
The reduplication of roots in Dak as in I E is extremely frequent, in both, as in other languages, developing iteratives which occasionally become intensives. The reduplication of Dak words is like Skt of but one syllable, usually but not always the root.
The suffix a, aya, which formed verb stems of I E roots usually becomes a, e, i in Dak as in old Eu. languages.
Ya seems to be rarely preserved: I E pak cook, Skt papakaya parch; Dak papakhya parch; I E agh say, Lat ajo for aghya say; Dak eya say. The Dak has many relics of the n of suffix na, which worked its way before the final consonant; I E tag touch whence I E tang, Lat tango; Dak tan touch. There seem to be relics of the other methods, which were however so closely akin to methods of forming nominal stems that they need not be discussed here.
Schleicher gives two methods of forming secondary verb stems: by suffix sa forming frequentatives; by suffix ya cause to be, forming transitive verbs from verbs, adjectives and nouns. Both are living suffixes extremely frequent and having the same force in Dak.
