Is there any grain of truth in this, I saw, quite popular assertion around tiktok and X?
According to historical reconstructions by Babaev & Samarina (2021), the presences of initial apical retroflexes /ʈ/ & /ʂ/ have shared evolutionary pathway in many Vietic languages, with /ʈ/ emerged when an ancient prefix combined with a rhotic sound *r, causing the tongue tip to curl back against the hard palate, and /ʂ/ emerged from the compaction of ancient sibilant-rhotic clusters (such as Proto-Vietic *sr- or *cr-), while retroflex flap /ɽ/ coda in May and Middle Vietnamese came from lenition and retraction of the simple alveolar trill *-r like May /pǎɽ¹/ < proto-Vietic *pər ('fly'). Modern Vietnamese lost final /ɽ/ which helped trigger the creation of the flat ngang-huyền tones. It would be suggesting that retroflexion is an ancient phenomenon in Vietic and can be accepted as proto-Vietic, albeit there was substantial influx of ʈ-words of Chinese origin borrowed into Vietnamese. How Middle Chinese, Mandarin, and Vietic gained and retain retroflexes while Southern Chinese dialects lack retroflexes altogether?
Vietnamese lacks initial /p/. So in the cases of French and English loanwords, do they pronounce it as /ɓ/ and /f/ instead?
I'm asking for why a word for "ground meat" that people put in Vietnamese Bún chả, often seen serves as a contrastive negative marker like example below.
Tôi chả thích nó. /toi ʧa tʰiʲk nɔ/
I don't like (at all).
vs generic negative không
Tôi không thích nó. /toi xoʷŋ͡m tʰiʲk nɔ/
I don't like it.
Thanks.
