If he really wants romance, here's how you can get /ø/ in English in three easy steps(: jello [d͡ʒɛl.loʊ̯] > [d͡ʒɛu̯.woʊ̯] > [d͡ʒø̞.wo] > [d͡ʒlø.wo](l reinsertion to ease articulation) > (more eases of articulation:) [t͡ʃ.lø.wo] > [t͡ʃ.løwo] > [t͡ʃʲ.løwo] and we all know where that [t͡ʃʲ.l] could turn into [ɟ.l] or [t͡ʃ.ʎ] yeah romance ass sounds ? wow, so d͡ʒɛl.loʊ̯] > [d͡ʒɛu̯.woʊ̯] > [d͡ʒø̞.wo] > [d͡ʒlø.wo](l reinsertion to ease articulation) > (more eases of articulation:) [t͡ʃ.lø.wo] > [t͡ʃ.løwo] > [t͡ʃʲ.løwo] > [t͡ʃʎøwɔ] > [t͡ʃʎwæ] > [t͡ʃjwa] > [t͡ʃ.jwə]
(these are a little more realistic but eh)There, more I guess: [[wɒɾɚ] > [wɶɾɚ] > [wɶrɚ] > [ɶːrɚ] > [œːrɚ] > [œːrə] > (loss of rounding from environment [oːr] > [or] > [orᵊ] > [or̠] > [oɰ] ~ [oɫ] or somesome [wɒɾɚ] > [wɒɻɚ] > [wɔʋɚ] > [wɔβ͡ʷə] > [wɔwə] > [wɔu̯ə] > [wø̞ːɵ̯] > [wø̠ː] [wɒdə] > [wɔdə] > [wɔd] ~ [wæd] > [wad] [wɒdə] > [wɶd] > [wɶdʰ] > [wɶtʰ] > [wɶt̪ʰ] > [wœθ̺] > [wœθ] > [wœð] > [wœz] [ð̞] > [z̺] > [z] So, /wœz/, /wad/, /wø:/, /ol/Yeah, I think my in world linguists would construct: *woʷl₂a or *wal₂, and to clarify L₂ is like H₂, but L₂ is hypothesized to be "any usual lateral sound or liquid rhotic"
