Lenition is a phonological change that is the result of the application of certain prefixes:[1]
px (/p'/) → p
tx (/t'/) → t
kx (/k'/) → k
p → f
t or ts → s
k → h
' (/ʔ/) → ∅
Conventional notation uses + to denote a prefix that causes lenition.[2]
Other effects
Since Naʼvi does not make the distinction between long and short vowels,[3] if the application of an affix results in two of the same vowels in a row, it usually is shortened to one.[4][Note 1] There is also some nasal assimilation of place.[5] Specific affixes listed hereafter will list there variants. Many prefixes combine with each other to form slight variants.
Naʼvi has a singular, dual, trial and plural number. The dual prefix is me+, the trial is pxe+ and the general plural is ay+. All of these prefixes cause lenition.[6] If the ay+ prefix causes a word to undergo lenition, the prefix may be dropped and the modified stem is also considered the general plural, and is known as the short plural.[7]
The prefix fì- indicates proximal deixis. When used as a plural, it becomes fay+.[9]
ex:
payoang
fish
→
fìpayoang
this fish
payoang → fìpayoang
fish {} {this fish}
The prefix tsa- indicates distal dexis. When used as a plural, it becomes tsay+.[10]
Other
There is also the prefix fne- which means a type, sort or class of the noun it is attached to.
Suffixes
The suffix -o marks the noun as indefinite (i.e. "some").
ex:
eylan
friend
→
eylano
some friend
eylan → eylano
friend {} {some friend}
The suffix -tsyìp is used as a diminutive/endearment suffix.[11]
ex:
utral
tree
→
utraltsyìp
bush
utral → utraltsyìp
tree {} bush
The suffix -fkeyk makes the noun refer to the state of the noun to which it is attached.[12]
Gender
Naʼvi does not have grammatical gender, but it has two suffixes that indicate the gender of a noun: the feminine suffix -e and the masculine suffix -an.[13] These are not mandatory.
ex:
karyu
teacher
→
karyuan
male teacher
→
karyue
female teacher
karyu → karyuan → karyue
teacher {} {male teacher} {} {female teacher}
Cases
Naʼvi is a tripartite language which means that the subject of an intransitive verb takes the intransitive case. The subject of a transitive verb takes the ergative case, which is -l on nouns ending with vowels and -ìl on nouns ending with consonants. The object of a transitive verb takes the accusative case, which is -t on nouns ending with a vowel and -ìt on nouns ending with a consonant.[14]
ex:
oel ngati tse'a
oel
I.ERG
ngati
you.ACC
tse'a
to see
oel ngati tse'a
I.ERG you.ACC {to see}
I see you
The dative case is -r or -ru on nouns ending with a vowel, and -ìr on nouns ending with a consonant.
The genitive case is -yä, except on nouns ending with o or u, where it is -ä, or nouns ending with -ia that become -iä.
The topical case is -ri on nouns ending with a vowel, and -ìri on nouns ending with a vowel.[14]
Nominalizers
The suffix -yu turns a verb into an agent noun.
ex:
slele
to swim
→
sleleyu
swimmer
slele → sleleyu
{to swim} {} swimmer
The prefix tì, in combination with the infix -us-, forms the gerund.[11]
The suffix -tswo creates a noun indicating the ability to do the verb.[15]
Naʼvi verbs primarily use affixes to modify their meaning. They do not conjugate for person, but for tense. Each affix has a specific location.
Positions
When an infix is added to a Naʼvi syllable, the infix goes after the initial consonant but before the vowel. There are three positions where an infix is added: the pre-first preposition, which goes immediately before the first position, the first position, which goes in the penultimate syllable, and the second position, which goes in the final syllable. If the verb is monosyllabic, all three positions go after each other. If the verb is a compound, the infixes only go in the head[16]
Pre-first position
Causative
The causative infix is -eyk-. When a causative verb is used, the ergative becomes the dative, and the accusative remains as it is.[17]
Reflexive
The reflexive infix is -äp-. When it is used with -eyk-, it always comes first (-äpeyk-)
1st position
Tense infixes
There are four types of tense infixes, which mark for the past, near past, general, near future and future tenses, and that mark for the general, imperfective, and perfective aspects[18]
The first type are the regular ones
Naʼvi has a few modal verbs, which when used, they must take the tense affixes and the modified verb must take the general subjunctive. The subject of the modal verb takes the intransitive case.[20]
ex:
emyu new syuvet ayfol yivom
emyu
chef.INTR
new
want
syuvet
food.ACC
ayfol
them.ERG
yivom
eat.SBJV
emyu new syuvet ayfol yivom
chef.INTR want food.ACC them.ERG eat.SBJV
The chef wants them to eat the food
2nd position
There are four infixes in this category, two indicating affect, two indicating speaker judgement. The infix -ei- indicate that the speaker is happy about the verb. The infix -äng- indicates that the speaker is unhappy about the verb.[21] The variant -eiy- of -ei- is used behind i,ì, ll, and rr[22] and the variant -eng- of -äng- is used behind i[23]
The infix -ats- is used to indicate that the speaker is uncertain of the accuracy of his or her statement. There is also the honorific infix -uy-.[12]
Adjectives are created with the -a- affix. Adjectives can go before or after the noun that they modify. If the adjective is before the noun -a becomes a suffix, and if the adjective is after the noun, a- becomes a prefix.[24]
Compare the two ways of saying the long river (kilvanriver, ngimlong)
ngima kilvan
and
kilvan angim
Participles
Naʼvi has an active participle infix -us-, and the passive participle infix -awn-[25]
Ability adjectives
There are two prefixes that mark ability tsuk- indicates that the subject (ergative) is able to perform the verb. It is negated with ke-. These turn a verb into an adjective [26]
From nouns
Nouns can be turned into adjective modifiers with the prefix le-. If this kind of adjective is used after the noun in question, the a- affix is usually dropped.[27] When it is used is after the prefix ke- they become kel-. If the ke- goes before le-, they become kel-.[28]
Copula
The Naʼvi copula is the verb lu. They can be linked to nouns or adjectives. Number is only required to be declared once in a phrase involving lu[29] Adjectives linked with lu are not required to have the -a- affix.
The verb lu can also be used in the sense of having. In this case, the possessor takes the dative suffix.[30]
Yes–no questions are formed with the word srak(e), which can go at the beginning or end of a clause (it has no e if it occurs at the end of a clause.
Pe question
The affix -pe+ is used to form question words when attached to a noun, which means which. It can go before or after the noun, and it causes lenition if placed before the noun. If it is a prefix, and the noun is plural, they will combine and become pem+ (dual), pep+ (trial) or pay+ (plural).
Naʼvi pronouns have the same declension as any other noun. The pronouns are declined for four persons: 1st person inclusive, 1st person exclusive, 2nd person, and 3rd person animate. Most of the plural forms of the various pronouns are made from the addition of the number prefixes to the singular.
Adpositions may go before or after the noun they modify. If it is before, then it is a separate word, but if after, it is an enclitic attached to the noun. For example, "with you" may either be hu nga or ngahu. When adpositions occur as prepositions, a few of them trigger lenition.
Relative clauses
Wikibooks has a book on the topic of: Na'vi/Syntax
Relative clauses are formed with the particle a. If the head noun is the ergative or accusative of the phrase it modifies, it is not present in the relative clause. If the head of the relative clause uses any other case or adposition, a resumptive pronoun is used.[33]
Conditionals
A conditional is use the words txo and tsakrr. The condition goes after txo, and takes the subjunctive case, then the consequent goes after the tsakrr (which is often omitted) and takes the relevant case.[34][35]
A counter-factual conditional uses the words zun for the condition and zel for the consequent, and uses the subjunctive in both clauses[35]
Naʼvi's native number system is an octal one. The numbers 0-7, 108 (8), and 1008 (64) are[36]
0
1
2
3
4
5
6
7
108
1008
kew
'aw
mune
pxey
tsìng
mrr
pukap
kinä
vol
zam
The powers of eight are combined with special prefixes to create multiples of powers of eight. These are the first syllable of the corresponding number, except for 1, which has none, and 2, which has me- instead of mu-. To create a number that is a power of eight plus a number from 1 to 7, the l of vol is deleted (except for 1), and the initial consonant undergoes lenition.[37]
Ordinals of the aforementioned numbers can be formed with the suffix -ve, but there are a few irregularities[38]
Naʼvi also has the numbers 'eyteight and naynnine as loanwords from English.[36]
