Well, you can of course start by laxing, then do all sorts of stuff with the laxness contrast. Just look at the English GVS. Also note that there is no obligation to phonemicize the laxness contrast! You can well rotate things around a bit while keeping them within a 5-phoneme set. Say, unstressed *i *u > *ɪ *ʊ > *ʲə *ʷə > /ja wa/; then unstressed *e *o > /i u/. Perhaps *a can further re-develop to unstressed /e o/ in some positions.Qwynegold wrote:Having a common five vowel systems, what can I do with vowels that involves stress? Is there anything besides laxing unstressed vowels, or tensing stressed vowels?
Adjacency to something that is palatal, labial, or pharyngeal, simply put.TinyMusic wrote:What are the typical conditions for palatalisation, labialisation, and pharyngealisation to happen?
Note also that these are in no way limited to "a vowel causes a consonant change". *lɟ > ʎɟ would also be palatalization; *wa > wɔ (as in English) would also be labialization; *iCɑ > ɪ̙Cɑ would also be pharyngealization. (Though when limited to vowels only, these are usually called "fronting", "rounding" and "retraction".)
