Iermansc 2.3

=Phase 1=

The transition from Late Latin to Proto Northern Romance. The Latin vocalic system was simplified, as stressed syllables started to take on quality instead of length distinctions while unstressed vowels tended towards elision. Final -M and -S were dropped. Vowels in unstressed syllables collapse to /a e i o u/ and in final syllalbes /a e i u/ (/o/>/u/).

Stressed Vowels

 * A generally remains /a/
 * AU remains /aw/
 * E, OE > /ɛ/
 * Ē, I, OE > /e/
 * Ī > /i/
 * O > /ɔ/
 * Ō,U > /o/
 * Ū > /u/

Examples
aurum > awru dūrus > duru oculus > ɔclu levis >	lɛve trēs > 	tre nivem > neve rota > rɔta caseolu > kasjol casa > kasa canem > kane camba >	kamba gallīna > gallina cattus > cattu tōtus > totu fōrma > forma ego > ɛgu

=Phase 2=

Stressed vowels continue to evolve, umlaut becomes productive.

The consonants /p t c/ evolve into /f s x/ in certain positions.

Word-finally, /a/ > /ǝ/, /e u/ disappear, /i/ > /ǝ/.

Stressed Vowels
