Kelun

Kelun or Kelunese (Classical Kelun: se Kệlungìz) is a recently discovered extinct language spoken by the indigenous Kelun people in the area around Qingdao, China.

The Kelun people were among the first to invent writing. Kelun is written using the Kelun syllabaries, which first appeared in year -1500 from an earlier logographic script that dates back to -2100. Kelun language texts came to an end around -300, but it is hypothesized that the language may have survived until around the year 0.

Classification
Kelun is generally considered to be an isolate, however, some believe that the language may be distantly related to the Koreanic, Tungusic, or Nivkh languages.

It is presumed that the language(s) of the nearby Yueshi culture is/are similar and related to Kelun, but no records of that/those language(s) exist.

Stages
The evolution of the Kelun language can be divided into 5 stages.

Proto-Kelun (before -1700)
This stage is written using the older logographic script, which is not currently deciphered, therefore no readable records of this stage exist.

Archaic Kelun (-1700 - -1200)
This stage is when the Kelun syllabaries were invented. In Archaic Kelun, there were no voicing or aspiration distinctions on consonants, and vowels had only one form and do not distinguish length and nasalization.

Classical Kelun (-1200 - -800)
Most Kelun texts were from this stage. Voicing and aspiration distinctions on consonants, and multiple forms and length and nasalization distinctions appeared during this stage.

Middle Kelun (-800 - -400)
Starting around -800, Kelun starts becoming increasingly analytic, marking the transition between Classical and Middle Kelun. During Middle Kelun, the number of noun cases has been reduced from 21 to just 4 (ergative, absolutive, genitive, and dative), the rest being marked with prepositions instead.

Late Kelun (-400 - 0)
Late Kelun is an isolating language with little inflection. The case system is completely lost, and the word order became strictly SVO.

Consonants
Classical Kelun has the following consonants: In the Kelun syllabaries, voicing and aspiration are distinguished with diacritics.

Vowels
Kelun has 8 basic vowels:

/a e i o u â ê ô/

In Classical and Middle Kelun, the vowels a, e, i, o, and u can have 3 forms:

/a e i o u/

/á é í ó ú/

/à è ì ò ù/

In Classical Kelun, the vowels â and ê can have 2 forms:

/â ê/

/â̛ ê̛/

The vowel ô can only have one form in Classical Kelun: /ô/.

Pronunciation of the different vowels and vowel forms are disputed, and may have differed between dialects. Classical and Middle Kelun feature a type of vowel harmony in which all vowels in a root word and its affixes must have the same form. The vowel forms â̛ and ê̛ correspond with á é í ó ú, while â and ê correspond with a e i o u or à è ì ò ù.

Traditionally, the Kelun syllabaries do not distinguish between the different forms of a vowel, which have to be inferred from context. However, all vowels can be nasalized (ạ), long (ā), or both (ạ̄), which the Kelun syllabaries distinguish with diacritics.

Syllable structure
The basic syllable structure is (C)CV(C), with an obligatory nucleus, an obligatory onset with one or two consonants, and an optional coda with only one consonant. It is presumed that all consonant clusters are allowed, however, this is debated.

"Ś"
The word ś, meaning "or" in all phases of the Kelun language and is the only known Kelun word without a vowel, is normally said as if it is part of the first syllable of the word (but written as a separate word), but if there are two consonants in its onset, ś may have been pronounced with a vowel following it, like śa. There is evidence that the vowel following ś may had been a in Late Kelun texts, where ś followed by a word beginning with two consonants is spelled as śa.

Nouns
In Classical Kelun, nouns always end in a consonant. They can be singular or plural, and they have 21 cases. In Middle Kelun, the number of noun cases was reduced to 4, and it was completely lost in Late Kelun.

A notable feature of Classical and Middle Kelun is that some body parts coming in pairs (i.e. hands, feet, arms, legs, eyes, ears) use the singular. This is because in Archaic Kelun, there existed a dual number to specify two of any noun, which merged with the singular in Classical Kelun.

In all known phases of Kelun, there has been a definite article (se in Classical Kelun, but agrees with nouns in case and number), but no indefinite article. Instead, absence of an article indicates that the noun is indefinite.

There are many derivational affixes for nouns, mostly infixes that go between the final vowel and consonant of a noun, but also some prefixes. There are no derivational suffixes, since suffixes are reserved for inflection.

Verbs
In Classical Kelun, verbs show aspect (imperfective, perfective, and habitual). The imperfective forms generally end in -a, perfective forms in -ê, and habitual forms in -ụ̄. These forms, without further marking, are infinitives.

Non-past tense conjugations for regular verbs (present if imperfective or habitual, future if perfective): Past tense conjugations are the same, but with -mị- added between the infinitive and the conjugational suffixes: Imperfective and habitual verbs also have a future form, which is identical to the past tense conjugations except with -đō̂- instead of -mị-: The subjunctive mood of a verb is shown with the prefix lā-. The imperative mood is shown by omitting the final vowel of the infinitive and adding the following suffixes: Kelun has an active, passive, and antipassive voice. The passive voice is expressed with -im- appended to the verb root, and the antipassive is expressed with -ix-.

A quirk of Kelun is that it does not have a verb for "to be", instead, nouns and adjectives have a verbal form expressing a similar meaning, which is shown with the suffix -ēx- for the stem. So, in Classical Kelun, the sentence "I am a tree" can be expressed as "(ẉe) kárḗxát", literally "(I) tree". ("kár" is the word for tree).

Adjectives
With little exception, most adjectives end in -ṛ. There are only 32 known adjective roots, instead, most adjectives derive from nouns or verbs using the suffix -aṛ or -ịṛ. Adjectives generally come after nouns.

Syntax
In Kelun, the basic word order is SVO, however, until around -700, word order can be different some of the time. Archaic, Classical, and early Middle Kelun are pro-drop languages, which means pronouns can be dropped if it can be inferred.

Vocabulary
About 1200 Kelun word roots have a known meaning. Another approximately 2000 word roots have been discovered, but their meaning is not known.

Pronouns
The basic pronouns are ẉe (first person), ñe (second person), and be (third person), but they inflect for number and case, with the -e taken off when suffixes are added. There is also a reflexive form of the pronouns, which has -ô instead of -e (ẉô, ñô, and bô), and does not inflect for number or case.

There is also a demonstrative pronoun (ṟè) and an impersonal pronoun (śe), both of which also inflect for number and case.

Relative pronouns are ṇe (who), ce (what), and ṛé (which), and interrogative pronouns are the same, but beginning with voiced consonants instead of voiceless ones (ne, đe, and ré). Indefinite pronouns are derived from the relative pronouns ṇe and ce, with prefixes lâ- (corresponding to some-), f- (any-), ṗu- (every-), and vi- (no-).

Conjunctions
Known Kelun conjunctions include là ("and"), ś ("or", the only known Kelun word that does not contain a vowel), gū́ ("but"), etc.

Numbers
Archaic, Classical, and some Middle Kelun uses a vigesimal (base-20) counting system. The numerals below are the root nouns, and the adjective form of all numerals uses the suffix -aṛ. Unlike other adjectives, they do not decline for number.

Around -500, Kelun borrowed the Chinese numeral system, which replaced its original numeral system.

Colors
The color system in Classical and Middle Kelun is unusual. There are 5 primary colors in Classical and Middle Kelun. Most languages with 5 primary colors have words for black, white, red, yellow, and green, but Classical Kelun have words for black, white, red, green, and blue, and uses the additive method of color mixing to create compound words for cyan, magenta, and yellow.
