Leten sciionron

Leten sciionron is the language of the people of Sicily (Sciio), descended from Classical latin, making a major divergence from other Latin dialects after 40 B.C., after the collapse of the roman empire in the war of Caesarean succession.

Classical Latin to Southern Italic Latin (0-400 A.D.)
Vowel Syncope

The antepenult of a word is stressed, unless the penult is long, in which case the penult is stressed instead. Stress shall be marked with an acute  ́ in phonetic transcription.

In (V)CVC(V) sequences  where the middle vowel is unstressed and short, the vowel is deleted.

Word final short vowels are deleted except in monosyllable

in (C)CVCVC sequences where both vowels are unstressed and short, the second vowel is deleted.

CCVCC sequences or CCVC sequences at the end of a word never have their vowel delected

Vowel shifts

VnC> ṼC. (n stands for any nasal consonant). In situations where this can occur there is never vowel syncope

/a/>/ɛ/ and /a:/>/ai/ in word internal syllables or when followed by a  syllable containing /i/, /e/, or /j/, regardless of stress

/a/>/ɔ/ and /a:/>/au/ in word final syllables or when followed by a syllable containing /u/, /o/, or /w/, regardless of stress

/ai/>/ɛ/

/au/>/ɔ/

/i/>/ɛ/ and /i:/>/e/

/u/>/ɔ/ and /u:/>/o/

/í/ and /í:/> /í/

/ú/ and /ú:/> /ú/

/e/ and /e:/> /ɛ/

/o/ and /o:/>/ɔ/

/é:/>/é/ and /ó:/ > /ó/

/é/>/í/ and /ó/>/ú/

Consonant Shifts 

Consonant clusters assimillate in voicing regressively. /s/ and /f/ always devoice the clusters they are in. Sonorants do not affect voicing.

Grammatical Shifts

Most neuter  nouns become masculine.

Neuter nouns usually used in the pural, like arma, become feminine singular first declension nouns.

Fourth declension nouns become second delcension

In analogy with the first and second delcensions, third declension nouns develop a genitive singular ending /ɛs/, so that all nouns have identical nominative plural and genitive singular endings

cum tends to be placed after the noun it modifies instead of before

Southern Italic to Sicilian Latin (400-000 A.D.)
Transposition

In CC sequences where the first consonant is a fricative, /l/, or /r/ and the second consonant is a plosive stop, the consonants are reversed. This occurs in all environments no exceptions.

/kj/ and /tj/>/t͡ɕ/

/gj/, /j:/ and /dj/>/d͡ʑ/

/sj/>/ɕ/

Grammatical Shifts

The dative is subsumed by the ablative except for the pronouns ig, tu, and pis.

The pluperfect and future perfect are lost

Cum fuses with the preceding noun to form the comitative case.

Grammatical changes

Debeir, puter, vvl,  noul, teneir and hebeir fuse to the infinitive that precedes them.

The last distinctions between the first and second declensions are lost. Feminine and Masculine fuse and gender disappears. The only remaining distinction is that many formerly feminine nouns lack the nominative singular -/s/ suffix.

Latin Panormi to Middle Leten sciionron (1300-1600 A.D.)
/pC/ where C is any plosive stop becomes /fC/

/kC/ where C is any plosive stop becomes /xc/

/tC/ where C is any plosive stop becomes /C:/
