nobody talks about how weird it is that a common way for phonemic distinctions in languages to develop is when there's a single phoneme that has different allophones in different context and some aspect of the conditioning environment for an allophone disappears but they keep saying the allophone in words that used to have the right environment and therefore they're now in distinction
like why do we keep using the old (former-)allophone instead of changing to what would normally be expected in that environment.
@Satsuma @gaditb how do they know it works tho
