Apostolic

Apostolic /ˌæpəˈstɑːlɪk/ (in Apostolic, Lingua Abodolia /ˈliŋ:ɣwaˌaboˈdoːʎa/), sometimes called Abodolic, was the official language of the Holy See in 100 C.D., spoken by ~2000 people, 1800 of these as a first language. It belonged to the Italic language family, stemming directly from Latin with an Italian substrate. This language was isolated from the rest of the world, since it was one of the only two light refuges in the demon realm of the Eastern Hemisphere.

Phonology

As people looked for softer speech, the Apostolic sound shift occurred.

Voiced plosive become fricatives Voiceless plosives become voiced Breathed plosives become fricatives
/b/ → /v/, /d/ → /ð/, /g/ → /ɣ/ /p/ → /b/, /t/ → /d/, /k/ → /g/ /ph/ → /f/, /th → /θ/, /kh → /h/

Apostolic also adopted some phonological traits from Italian:
C = /ʃ/ before /e/, /i/, /j/; /k/ elsewhere.
G = /ʒ/ before /e/, /i/, /j/; /g/ elsewhere.
/kC/ → /C/ or /CC/
Final consonants disappear, plurals formed differently from -s or not at all.

/r/ must start a syllable, ergo dre = /di̯ˈre/, not */dre/; servori = /serˈvɔ.ri/, not */serˈvɔr.i/

Orthography

Most letters in Apostolic represent their IPA phonemes, with these exceptions:
C and G palatalize before E, I, and Y.
J only appears at the starts of words. I makes the /j/ sound medially and finally.
LI makes the /ʎ/ sound, not */lj/
N becomes velar (/ŋ/) before velar plosives and fricative K (/k/) and G (/g/, /ɣ/).
O becomes open-mid (/ɔ/) before liquids L (/l/) and R (/r/).
Q does not appear individually except to represent itself (pronounced /kwe/). QU, however, makes the /kw/ sound.
S may become voiced (/z/) after voiced plosives B (/b/), D (/d/), G (/g/).
TH represents respectively.
U represents semivowel /w/ before unstressed vowels. The letter W only appears at the start of words.
X represents the vowel cluster /ks/, or sometimes /gz/ when unstressed.
Y only appears in loanwords, representing the rounded vowel /y/. Diphthongs AE and OE represent /ai̯/ and /ɔi̯/.

All together, Apostolic officially has a 26-letter alphabet: A, B, C, D, Ð, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Z.

Morphology

Nouns

Apostolic has 5 categories of nouns: A-stems, from Latin 1st declension and 2nd declension neuters; E-stems, from Latin 3rd and 5th declensions; I-stems, from Latin 2nd declension masculine; O-stem, from some rare cases of 3rd declension nouns; and U-stems, from Latin 4th declension.

E-stem ðie, bade ðie, bade
I-stem servi, bui servi, bui
O-stem tempo, senado tempoe, senadoe
