Proto-Human language

Proto-Human was the most recent common ancestor of the languages of Etrand and former Hulra, being spoken from 1300 BEKE to roughly 800 BEKE in Etrand and Hulra.

The language was poorly attested, and most written records come from High Elven and Wood Elven sources. However, in Hulra, rich traditions of written literature were starting to developed already in the transition period between Proto-Human and Old Hulran, between 850 BEKE and 750 BEKE, while Etrand remained a land of illiteracy until the Kingdom of Etrand was founded in 0 BEKE/AEKE.

Consonants

 * Loss of palatal and post-alveolar consonants
 * The retroflex nasal [ɳ] merged with the retroflex rhotic [ɻ], which in turn eventually merged with the plain alveolar rhotic /r/ (see below)
 * The retroflex series [ʈ͡ʂʰ ʈ͡ʂ ɖ͡ʐ ʂ ʐ ɭ ɻ] merged with the plain alveolar /t͡sʰ t͡s d͡z s z l r/ series.
 * The palatal nasal [ɲ] and lateral [ʎ] merged with the palatal approximant /j/.
 * The voiceless palatal sibilants /t͡ɕʰ t͡ɕ ɕ/ became /ç/. The voiced palatal sibilants /d͡ʑ ʑ/ merged with /j/.
 * The palatal rhotic [ɺʲ] merged with the plain alveolar /r/.
 * Fricatization: the aspirated stops /pʰ tʰ kʰ kʷʰ/ became fricatives /ɸ θ x xʷ/. The aspirated affricate /t͡sʰ/ lost its aspiration and merged with /t͡s/.
 * Fricatization of intervocalic /b d/ to [β ð]
 * Lenition of /g gʷ/ to /ɣ ɣʷ/ everywhere except after nasals
 * Merger of the guttural rhotic /ʁ/ with the plain alveolar rhotic /r/
 * Loss of /ŋ/ and /ŋʷ/
 * Syllable-onset /ŋ ŋʷ/ became /ɣ ɣʷ/
 * Syllable-coda /ŋ/ became /n/

Grammar

 * Distinction between "personal plural" and "neuter plural" fell out of use, resulting in one uniform plural grammatical gender.
 * The locative case disappeared, replaced by simply using locative prepositions before nouns in the accusative case.
 * A general shift Proto-Elven's preference towards postpositions to a strong preference towards prepositions.
 * Shift to a subject-verb-object word order. (Proto-Elven had subject-object-verb)

Consonants
The voiced non-sibilant fricatives [β] and [ð] appeared only as post-vocalic allophones of /b/ and /d/. They also served as intervocalic allophones of their voiceless counterparts /ɸ/ and /θ/.

The voiced velar stops [g] and [gʷ] appeared only as allophones of /ɣ/ and /ɣʷ/ after nasals.

The velar nasal [ŋ] was the allophone of /n/ before /k x ɣ/. Do note that /nɣ/ was pronounced as [ŋg], not [ŋɣ].

The labio-velar nasal [ŋʷ] was the allophone of /n/ before /kʷ xʷ ɣʷ/. Do note that /nɣʷ/ was pronounced as [ŋʷgʷ], not [ŋʷɣʷ].

Proto-Human's one and only rhotic phoneme /r/ had a variable pronunciation, ranging from apico-alveolar to post-velar / pre-uvular. It likely depended on the surrounding consonants, and the post-velar allophone likely also had a slight fricatization ''(similiar to real-life Czech <ř> /r̝/, just post-velar / pre-uvular instead of alveolar). ''Likely, [r̺] was used "normally", and [ʀ̟] was used after velar consonants, maybe even before back vowels word-initially.

The palatal fricative /ç/ was a rather unstable phoneme, and it likely merged with /x/ before splitting up into the descendant languages. Likewise, the voiced labio-velar fricative /ɣʷ/ was also an unstable phoneme. In all descendant languages, [ɣʷ] merged with /w/, and /nɣʷ/ [ŋʷgʷ] merged with /mb/. The fact that these mergers happened in both Old Etrandish and Old Hulran seem to imply that the sound shift could have happened at an earlier point, most likely in Late Proto-Human.

Monophthongs
The laxed vowels [ɪ ʊ] only appeared as allophones of short /i u/ in closed syllables where the coda-consonant was a velar consonant. That also extends to [ŋ], which itself was the allophone of /n/ before velar consonants.

While the long /eː/ was a close-mid [eː] and the long /ɛː/ was open-mid [ɛː], the short /e/ was likely truly middle, neither [ɛ] nor [e], but in between the two: [e̞]. Or, according to other theories, it could have been a close-mid [e], like it's long counterpart.

Grammar
Proto-Human was a subject-verb-object and synthetic language.

Nouns
The various cases had the following functions:
 * The nominative case usually marks the subject of the sentence.
 * The genitive case marks ownership. For example, "atrandan ríkta" means "(the) Kingdom of Atrand".
 * The dative case usualy marks indirect objects, similar to the use of English "to" and "for"
 * the accusative case usually marks direct objects, ones that are being directly targeted.

The locative case was not carried over from Proto-Elven. Instead, it was replaced by using nominative together with locative prepositions.

Verbs

 * The infinitive is marked by -iri, just like Present Simple.
 * Adding an extra -r at the end turns the verb perfect. An example:
 * "seffiri" means "to make someone/something beautiful". It is in Present Simple.
 * "seffiga" is the same verb, but in Future Simple instead. For example, "you will make her beautiful".
 * "seffigar" is the same verb, but in Future Perfect instead. For example, "you will have made her beautiful".

Adjectives
Adjectives have three forms in Proto-Human:
 * Normal adjective: -ani
 * Comparitive adjective: -aneri
 * Superlative adjective: -anagi

Adverbs
Adverbs have three forms in Proto-Human:
 * Normal adverb: -atn
 * Comparitive adverb: -artn
 * Superlative adverb: -ang

Inclusive or vs Exclusive or
Proto-Human - and by extension, all of its descendant languages - distinguish between the "inclusive or" and the "exclusive or". The earlier means, "either A, B, or both of them", while the latter means "either A or B, but not both of them - never both of them".
 * The word for the inclusive or is
 * The word for the exclusive or is

Numerical system
Proto-Human is said to have regressed from Proto-Elven in the numerical sysem. While the octal system was dropped altogether, adopting a purely hexadecimal system, the old and well-functioning postfix system was dropped, and replaced with unique names for all the powers of 16, making for a clumsier, less convenient, and overall more primitive system.

Numbers from 0 to 16

 * 0: mar
 * 1: an
 * 2: fán
 * 3: gwen
 * 4: rai
 * 5: tsai
 * 6: zai
 * 7: gai
 * 8: step
 * 9: rawan
 * 10: raufán
 * 11: raugwen
 * 12: raurai
 * 13: rautsai
 * 14: rauzai
 * 15: raugai
 * 16: raustep

Numerical postfixes

 * 16 power 1: -ap
 * Denotes the first power of 16. For example, "anap-an" means $$((16^1) * 1)+((16^0)*1)$$, or 0x11, or simply 17 in decimal.
 * Logic would suggest the number 16 - 0x10 in hexadecimal - be said as "anap" - but it is actually "raustep". This is a holdover from Proto-Elven.
 * double: -ip
 * Denotes the second power of 16. For example, "anip-an" means $$((16^2) * 1)+((16^0)*1)$$, or 0x101, or simply 257 in decimal.
 * When used as a noun - especially plural, and especially in casual usage - the word can also be used as an equivalent of "hundreds".
 * quad: -kwat
 * Denotes the third power of 16. For example, "ankwat-an" means $$((16^3) * 1)+((16^0)*1)$$, or 0x1001, or simply 4097 in decimal.
 * When used as a noun - especially plural, and especially in casual usage - the word can also be used as an equivalent of "thousands".
 * octa: -ét
 * Denotes the fourth power of 16. For example, "ankwat-an" means $$((16^4) * 1)+((16^0)*1)$$, or 0x10001, or simply 65537 in decimal.
 * octa: -kwét
 * Denotes the fifth power of 16. For example, "ankwét-an" means $$((16^4) * 1)+((16^0)*1)$$, or 0x100001, or simply 1048577 in decimal.
 * When used as a noun - especially plural, and especially in casual usage - the word can also be used as an equivalent of "millions".
 * negative: -nil
 * Used to postfix a negative number. For example, "an" means 1, while "annil" means -1.
 * Ordinator: -iz
 * Turns a cardinal number into an ordinal number. For example, "an" means "one", while "aniz" means "first".
 * Radix point: thwir
 * Literally means "full", it separates the integral part of a number from the fractional part. For example, "an thwir raustep" means 0x1.F, equivalent to the decimal 1.9375.
