The purpose of this module is to automatically generate conjugation tables for Navajo verbs, similar to the output of the {{nv-verbtable}} template.

Introduction

edit

This module is originally based on Kari's thesis (1978) with a sizeable number of additions, adaptations and fixes.

Overview of the supported features:

Covered Not covered
Mode - Imperfective (∅, ni)
- Perfective (yi, ni, si)
- Future (∅, yi)		 - Iterative
- Optative
Persons - 1 to 4 - Unspecified
- Spatial
Numbers - singular
- dual
- plural
Paradigms - highly to fairly productive
- highly to fairly regular		 - unproductive or rare
- too irregular
- seriative
Stem - must be provided

Usage

edit
  • function
Use conj when invoking the module directly, and show when invoking from a template.
|1=
Mode, to choose from: impf, perf or fut.
|2=
Aspect marker (position VII), to choose from ∅, ni, si,yi or yii.
|3=
Classifier (position IX).
|4=
Stem (position X) must be provided by the user.
|disj=
Disjunct prefix (position 0/I).
If needed use : to separate multiple prefixes.
|obj=
Object prefix (position IV/V).
|conj=
Conjunct prefix (position VI).
If needed use : to separate multiple prefixes.

The input prefixes can usually be written in their usual orthography with the glottal stop, but mind the following special conventions:

  • a or ʼi
for either the a-away disjunct prefix or the unspecified object prefix.
  • á or ʼí
for the á-thus disjunct prefix
  • ho or hwi.
for the spatial object prefix
  • Pi
for the b/y indirect object alternation.

As some verbs exhibit a number of irregular alternations, additional options are provided for the user to help the module generate the correct form.

  • |nodevoice=1
Do not devoice stem initial consonant even after 1st person singular sh- or 2nd person duoplural h-.
  • |d-effect=
Provides the form taken by the stem initial consonant when following the 1st person duoplural iid- prefix, when different from the expected d-effect.
  • |nospread=1
Do not spread disjunct prefix high-tone to conjunct pre-stem syllable.
  • |hop=far
Perform glottal stop hopping further right inside a 2nd singular prefix.
  • |dashift=
=1
Shift to si- conjugation in the perfective plural for all persons.
=3
Shift to si- conjugation in the perfective plural for 3rd and 4th persons only.
  • |neuter=
=ni
Use ni- as the prefix for 3rd and 4th persons in ni- conjugations.
=∅
Use ∅- as the prefix for 3rd and 4th persons in ni- conjugations.


Finally, in case the module is unable to generate the correct output for a particular form using the general rules, it is possible for the user to provide it explicitly with the following optional arguments:

  • |1sg=
  • |2sg=
  • |3sg=
  • |4sg=
  • |1dl=
  • |2dl=
  • |1pl=
  • |2pl=
  • |3pl=
  • |4pl=

Alternative usage

edit

In the usage describe above, 4 parameters are mandatory (mode, aspect, classifier, stem) while the others are optional (including disjunct, object and conjunct prefixes).

There is also an alternative usage of the module with 7 mandatory parameters for mode, disjunct, obj, conjunct, aspect, classifier and stem, allowing a somewhat more condensed expression.

See examples below.

Examples

edit 
{{#invoke:nv-conj|conj|impf|∅|∅|cha}}

or using the wrapper template {{nv-conj}} : 

{{nv-conj|impf|∅|∅|cha}}
IMPERFECTIVE singular duoplural plural
1st person yishcha yiicha deiicha
2nd person nicha wohcha daahcha
3rd person yicha daacha
4th person jicha dajicha 


{{nv-conj|perf|disj=kʼi|obj=y|conj=di|yi|∅|lééł|d-effect=ly}}

or using the condensed usage: 

{{nv-conj|perf|kʼi|y|di|yi|∅|lééł|d-effect=ly}}
PERFECTIVE singular duoplural plural
1st person kʼidíílééł kʼidiilyééł kʼidadiilyééł
2nd person kʼidíínílééł kʼidoolééł kʼidadoolééł
3rd person kʼiidíílééł kʼideidíílééł
4th person kʼizhdíílééł kʼidazhdíílééł 


{{nv-conj|fut|disj=Pí|obj=ho|yii|ł|ʼááł}}
FUTURE singular duoplural plural
1st person bíhwiideeshʼááł bíhwiidiilʼááł bídahwiidiilʼááł
2nd person bíhwiidííłʼááł bíhwiidoołʼááł bídahwiidoołʼááł
3rd person yíhwiidoołʼááł yídahwiidoołʼááł
4th person bíhwiizhdoołʼááł bídahwiizhdoołʼááł


Note that the following call would have given the same output: 

{{nv-conj|fut|disj=Pí|obj=hwii|∅|ł|ʼááł}}

As a matter of fact, it might be sometimes useful to try shuffling prefixes around until the correct forms be generated.

Unsupported paradigms

edit

Imperfective

edit
  • seriative
  • ...

Perfective

edit
  • "make"-verbs based on the -dzaa, -laa or -ʼį́į́d stems.
  • paradigms with ní ~ néé ~ née ~ nées alternations.
  • paradigms with díní ~ déé ~ dées alternations.
  • paradigms with di-si ~ diiz alternations.
  • most of yini-/yíní- paradigms.
  • seriative
  • ...

Future

edit
  • seriative

--[[
Based on Kari's paper (1978)
with several personal additions, adaptations and fixes. 

NOTES:
- Lua regex are very expensive, had to scale back my all-regex coding paradigm. 
- In order to facilitate usage of Lua regex (which are very limited), consonants are converted to a one-symbol format (ex: q for k', č for ch...), then rules are applied, then the word is converted back to conventional orthography. 

TODO:
- seriative,  
- "make" verbs in the perfective, 
- get rid of the ":" altogether as a formative boundary.
