Navajo

Etymology 1

Represents multiple homophonous thematic and aspectual prefixes of position I and VI, whose exact meaning and etymology remain mostly speculative.

Prefix

di- (position I)

1. fire, near or into it

   • diidiłjeeh ― to make a fire

► Navajo verbs with disjunct prefix di-

di- (position VI)

Young and Morgan (1987) identify 14 or so thematic prefixes, among others:

1. fire, light

   • diidiłjeeh ― to make a fire

2. arms and legs

   • dilʼéés ― to step, to place one's foot

3. extension, elongated shape
4. noise, sound, oral, food, sensory

   • dilwosh ― to shout
   • disééh ― to belch
   • yidiitsʼį́į́h ― to hear it

5. color (see also dini-)

   • dinilgai ― whitish

6. relinquishment, relief

   • yą́ą́ʼdíłgééd ― to uncover it by digging
   • bidizóóh ― to subtract it

7. sanctity

   • diyin ― holy

8. Unclassified, often entering in the formation of other prefix compounds

   • kʼiidilé ― to plant it
   • yidiséí ― to crumble it
   • hadii- ― from end to end
   • díní- (prolongative)
   • tádi- (diversative)
   • bibadi- ― to exhaustion

Four modal-aspectual uses are also distinguished:

1. Forms a number of inceptive verbs, with a (Ø/si) paradigm.

   • dighááh ― to start to go

2. Forms a number of inchoative verbs, with prepounded dah and a transitional (yii/yii) paradigm.

   • dah diighááh ― to start off, to set out, to leave

3. Forms the future mode of all active verbs along with the progressive yi-.

   • doogááł ― he will go
   • didoogááł ― he will start to go
   • dah didoogááł ― he will start off

4. Forms a number of neuter adjectivals.

   • dijool ― spherical, chubby

► Navajo verbs with prefix di-

Etymology 2

Probably cognate with a prefix of similar shape occurring in other Athabascan languages a reflexive possessive pronoun.

Probably cognate with classifier -d- marking passive and reflexive verbs.

Prefix

di- (position IV)

1. Personal prefix used in combination with the prefix of position I à-, marking the reflexive verbs. It always triggers a classifier shift (Ø → d, ł → l).

   yishchʼid ― I'm scratching it

   nishchʼid ― I'm scratching you

   ádíshchʼid ― I'm scratching myself

   ánáádíshchʼid ― I'm scratching myself again
