Simple

Simple, or the Simple Vowel System, is a vowel system that was considered on the vowel ballot.

Proposal
On April 30, 2017 at 15:18 UTC, Dominick DiMercurio II proposed the system, stating:"There are three vowels /a/, /i/ (with allophones /ɪ/, /e/, /e̞/, /ɛ/, /ɛ̝/ in free variation), and /u/ (with allophones /ʊ/, /o/, /o̞/, /ɔ/, /ɔ̝/ in free variation). There are no diphthongs."

Election
On May 6th, after having received less than 10 votes, the Simple Vowel System did not advance to the second round. As such, the vowel system is not part of the demlang.

Legacy
While Simple did not win, it did inspire 3 Short & 3 Long, the vowel system that did eventually win.
