Indeyivroplu

Indevroplu (indėvroplu / индевроплу 🔊), also known by its older name Indeyivroplu, is a personal constructed language (conlang) that is classifiable as both an engineered and auxiliary language due to its goals of maintaining an absolute logic in structure, and reforming connections between all living branches of the Indo-European (I.E.) language family. In aspiration of this, the vocabulary of Indevroplu is almost entirely a posteriori, rooted from the following languages: Persian, Spanish, German, Russian, Greek, Armenian, Albanian, and Welsh (in decreasing order of prevalence). There are however some morphemes (word roots) loaned from non-I.E. languages, and even a few unique a priori roots. I first published my work on this conlang in 2024, and still continue to expand its vocabulary.

The structure of Indevroplu is holistically a mixture between common Indo-European patterns and a few inspirations received from other world languages and conlangs. It is a synthetic language, notable for its inflections based on part of speech, frequent agglutination (compounding of words), and lack of grammatical gender, cases, or articles.

Each of the 6 vowels can be written with an extra diacritic (aeėiou → áéëíóú) to indicate stress over a syllable when not following the default stress pattern. This is however optional and often omitted, because no two words/morphemes are distinguished only by stress.

¬use second IPA value if <r> is geminated

Beyond Latin and Cyrillic, there is also a unique featural script created for Indevroplu.

Phonology

Standard Indevroplu has a perfectly phonemic orthography, where one grapheme always corresponds to one phoneme and vice versa, without morphophonological effects. Note that all three unvoiced plosives are always aspirated.

Prosody

When pronouncing words, the division between syllables in the case of a consonant cluster at a syllable boundary is done by equally splitting the consonants if an even cluster, or putting 1 more consonant in the 2nd syllable if an odd cluster. The only exception to this method is with glides (see "Phonotactics" below).

Stress

Word stress in Indevroplu falls by default on the final closed syllable. Based on the part-of-speech inflections, this equates to the ultimate syllable for verbs, and the penultimate for all else. An earlier syllable can be stressed instead, but only through the usage of a diacritic (á,é,ë,í,ó,ú). Monosyllabic words receive primary stress.

1. pre - [ˈpʰɾɛ]
2. andir - [anˈd̪iɾ]
3. gišera - [giˈʃɛ.ɾa]
4. prėğnorjėr - [pʰɾɪ̞.ɣnɔˈɾjɪ̞ɾ]
5. nėkonlunkora - [nɪ̞.kʰɔn.lu̞nˈkʰɔ.ɾa]
6. húndatğramju - [ˈhu̞n.d̪at̪ʰ.ɣɾa.mju̞]
7. luskorzorkėgiohu - [lu̞s.kʰɔɾ.zɔɾ.kʰɪ̞.giˈɔ.hu̞]

Intonation

Stress in Indevroplu is realised as a dynamic accent, meaning loudness is the distinguishing factor as opposed to tonality.

Phonotactics

Indevroplu has quite a high level of freedom when it comes to phonotactics, meaning that it allows a variety of consonant clusters. There are 3 rules governing the scenarios where consonant clusters are permitted to break the Sonority Sequencing Principle:

1. = A single syllable may contain multiple adjacent nasals, fricatives, or plosives, as long as two of the same phoneme (disregarding voicing) don’t occur adjacently within the syllable.
2. = <r> placed directly after a nasal, fricative, or plosive when in the syllable coda will make those two consonants behave as a single unit together, but <r> cannot be followed by another consonant in that syllable.
3. = Fricatives and stops are both regarded as if having the same priority ranking, and therefore may be placed interchangeably in a cluster.

Additionally, there is a 4th phonotactic rule:

• Individual morphemes (word stems) must always end in a consonant. Thus when a morpheme ends in a front vowel in its original language, it converts to <j>, while a final back vowel becomes <h>.

  This rule exists to more clearly mark the start of an inflection in a word, since all inflections begin with a vowel or semivowel.

Morphology

Inflection

Words in Indevroplu are inflected for part of speech. In this manner, all words consist of base morphemes which are given one of the following suffixes: -u (noun), -a (adjective), -i (adverb), -e (preposition/conjunction), -o (pronoun), -ė (interjection), -ir (infinitive verb).

1. prend- = related to comprehension

   prendu = understanding (n.)

   prendir = to understand (inf. v.)

   prenda = understood (adj.)

   prendi = understandingly (adv.)

   prendė = OK / understood (intj.)

2. loğ- = related to reason

   loğu = reason, logic (n.)

   loğe = because (conj.)

   loğa = logical (adj.)

   loği = logically (adv.)

   loğir = reason (inf. v.)

3. m- = related to 1st person

   mo = I, me (pron.)

   ma = my (adj.)

Conjugation

Verbs in Indevroplu conjugate according to 3 persons, 2 numbers, 3 tenses, and 5 moods. Refer to the below conjugation tables:

1P = I/we; 2P = you; 3P = they || sg. = singular; pl. = plural

	pl.	-jėrf				-jėf

Gerund
-end + (conjug.)
Subjunctive
-sj + (conjug.)
Conditional
-šp + (conjug.)
Interrogative
megėj- + (verb stem) + (conjug.)

Subjunctive is normally indicated in English by the word "if," and conditional is indicated by "would." The subjunctive and conditional moods are related in that both deal with hypothetical situations, where conditional is dependent on subjunctive. For details refer to: Grammatical Mood.

Not included here is the past participle form because it is treated in Indevroplu as an adjective, with the suffix "-ka"

The interrogative mood using the prefix megėj is used in all question sentences that do not contain question words, all of which begin with čė.

Syntax

Loanword Adaptation

Approximately 93% of all word stems in Indevroplu are from natural languages, and around 78% total are of Indo-European origin. When loaning any word, research was done into its etymology in an effort to loan only the base morpheme, leading to them not always being immediately recognizable. Here are some examples:

1. ips- is the word stem relating to "high/height", loaned from Greek ψηλός (psilós) "high", but made to reflect the more basic root ύψος (ípsos) "height".
2. soň- is the word stem relating to "sleep", loaned from Spanish sueño "sleep" (n.), but made to reflect the more basic root soñar, even if in Spanish it changes meanings to "dream" (v.).

Indeyivroplu implores a strictly phonetic system for the adaptation of loanwords, rather than the more internationally common phonemic method. This means that the individual phones of the word in the root language are converted to their closest approximation in Indeyivroplu systematically, while its original spelling is disregarded.

1. fxas.elu [fχas] meaning "France", loaned from French "France" [fʁɑ̃s]
2. duj.e [d̪u̞j] meaning "through", loaned from German "durch" [dʊɪ̯ç]
3. njéuh.u [ˈnjɛ.u̞h] meaning "bird", loaned from Mandarin "鳥" [ni̯ɜʊ̯²¹⁴]

   note here the 4th phonotactic rule coming into play

Agglutination

Indevroplu employs a frequent usage of agglutination. In the creation of the language, there was a preference towards forming new words using existing word stems rather than directly loaning the foreign word.

When making compound words there is no interfix used, so morphemes are simply placed directly after each other, with only the final morpheme being inflected.

1. fligmuku ("bat") = flig.a + muk.u ("flying" + "rat")
2. kajskorxonu ("laboratory") = kajs.u + kor.ir + xon.u ("trial" + "to work" + "house")
3. inždora ("farthest") = inž.i + dor.a ("most" + "far")

The only cases where a non-final morpheme ever gets an interfix are for: morphemes ending in an obstruent + <r> sequence, and the 28 total "ghost-syllable" morphemes, named so because they consist of 1 syllable onset followed by -ė in all positions except word-finally. They are:

d, dj, fr, fsj, g, h, j, k, l, m, n, p, pr, s, sr, st, sj, šp, t, tr, tš, v, vj, xv, zd, zg, ž, žm

1. stė.ob.ronir "surf" versus on.sti "then" (as opposed to on.stė.i)
2. lė.jek.hu "syllable" versus elin.lu "Greek" (as opposed to elin.lė.u)
3. ultrėkluga "ingenious" versus ultri "extremely" (as opposed to ultrė.i)

Constituent Order

Indevroplu uses the order Subject-Verb-Object (SVO), and indirect objects come before direct objects. Adjectives and adverbs directly precede the noun or verb they modify, unless a subject pronoun is attached to the verb (only in 3rd person), in which case it will go between the adverb and verb. Also, prepositions must uninterruptedly connect their subject with the object. Outside of these rules, there is some flexibility allowed in word order, especially when there are consecutive words of the same part of speech.

"I have all of your blue books."

1. tenar fsja ta sina girkju.
2. tenar ta fsja sina girkju.
3. tenar sina ta fsja girkju.
4. ...

"You drove to the office this evening because of the rain."

1. loğe rígėňu etábėndi ronkuruz eose dafterxonu.
2. etábėndi ronkuruz eose dafterxonu loğe rígėňu.
3. ...

Additional Details

The meaning of the name Indevroplu, natively indėvroplu, is "Indo-European speech." The older name Indeyivroplu comes from a transcription of Russian "индоевропе́йский."

Setting

The fictional region in the world where Indevroplu would be spoken is in rural communities in Mehedinți county, Romania, near the Serbian and Bulgarian borders. It is named Melézaf, transliterated to Romanian as Melezaf and to Bulgarian and Serbian as Мелезаф. This location was chosen because it is the calculated geographic midpoint between the capitals of the primary home nations of Indevroplu's eight constituent languages (Iran, Spain, Germany, Russia, Greece, Armenia, Albania, & Wales).

Writing Conventions

• Capitalization functions a bit differently from other languages using the Latin script, in that capitalization is only used at the start of proper names, thus the first word of an Indevroplu sentence will not necessarily be capitalized.

• In the formal register, a hyphen (-) should be appended at the morpheme boundary of all proper names.

• If typing diacritics is unsupported, those 5 letters of the Latin script should be written as their base form plus an apostraphe ('). For Cyrillic, the 3 special letters become their base form plus ь.
