I wonder, are retroflex consonants rare? Admittedly, my language doesn't use them to the same degree as e.g. Hindi, but at least I'm still "acclimatised" to the basic retroflexes found in my dialect.
As a point of closure in articulation, retroflex consonants are quite common, usually in complex alternation with alveolars (via, for example, feature spreading from vowels). Alveolar vs retroflex contrasts, on the other hand, are much less common, and sizable bulk of what does exist is a South Asian areal feature. Outside of South Asia, I wouldn't go so far as to call retroflexes rare, though perhaps "notable".
I see, retroflexes aren't unusual as such, it's just that in most cases they don't contrast with their alveolar counterparts — so an English speaker would have trouble hearing the difference, but not find the sound itself particularly strange.
It's also intrigues me how Old English [r] became [ɹ~ɻ] and Old Norse [l rð] became [ɽ]. I know it's pretty much the whole point of "diachonicity(?)", shit happens, but some changes still remain quite interesting. At least for /rn rt rd rs/ → [ɳ ʈ ɖ ʂ] there is a very clear underlying pattern.
That is interesting. I know next to nothing about English/Germanic, but lateral<->retroflex alternations are phonetically motivated and thus reasonably common. Was there really a merger between [l] and [rð] in Old Norse? That's more surprising than the retroflexion!
As far as I know, some dialects of Norwegian, Swedish, and for certain some Norse dialects in Finland (Finland-Swedish doesn't have retroflection), have merged [l rl rð] to varying degree. In Swedish [ɽ] is probably quite archaic today and I think it remains in only a few dialects, [l] becoming [ɽ], but [rl] becomes [ɭ], and I'm uncertain about [rd]. In Norwegian it should be fairly common, depending on the region, except [rl] becomes [ɭ] as in Swedish, but [l rd] becomes [ɽ] in dialects where it is present. In Norwegian there might even be contrast, possibly making them contrastive phonemes /l ɽ/.
My dialect has all three [l rl rd] → [ɽ], and so far the distribution of [l ɽ] seems to be codependent? (is that the word), although there might be some positions where the two have some minimal contrast.
An underlying [l] occurs
- initially {hl- l-}
- geminate {ll}
- next to /n t d s/ (usually in the root) ← position of the tongue inhibits flap
- after /i(ː) y(ː)/ ← position of the tongue inhibits flap
- in some cases after /ɛ/ ← perhaps influence or earlier geminate
An underlying [ɽ] occurs
- in come cases before /n t d s/ (usually in inflection or derivation)
- in place of [rd rl]
- elsewhere
