Etymology

Proto-Athabaskan *də- (valency decrease), from Proto-Na-Dene *də- (signaling valency decrease); cognate with Haida -d-, Eyak -d-, and Tlingit -d- (reflexive suffix).

Pronunciation

IPA^(key): /t-/

Prefix

d-

the d- classifier or valence-change prefix, a detransitivizing prefix of active verbs that modifies the transitivity or valence and grammatical voice of a verb, occurs in most passive, mediopassive, reflexive, and reciprocal verbs that are derived from verbs with a ∅- classifier; it produces the agentive passive verb forms
yizéés ― he’s singing it (yi-∅-zéés)

yidéés ― it’s being sung (yi-d-zéés)

Usage notes

The d-classifier rarely appears as a /d/, but instead usually triggers a process called d-effect, which can voice voiceless consonants and add a glottal stop before nasals and approximants.

Prefix

d- (class B & C infixed pronoun)

him (triggers nasalization)
it (triggers lenition)

Usage notes

This form merges with the prefixes ad-, aith-, ess-, and in- to form at-; with com- to become cot-; and with fris- become frit-.

The neuter singular form is often used pleonastically, in cases where the direct object is mentioned explicitly in the sentence (and is not necessarily even neuter singular).
