Postalveolar sounds

Hi, Do you know whether there is a difference between [sʲ] and [ɕ] (that is, a difference between the palatalized alveolar sibilants and the alveolo-palatal "fully palatalized" postalveolar sibilants)?

I don't really know. I suspect that there is, by some formal definition, but I have no idea if that difference matters in practice.

I happened to come across this discussion and just had to butt in. In Russian, [sʲ] and [ɕ] are two entirely different sounds, as demonstrated by the minimal pair ще́ли (ščéli, “cracks, fissures”) [ˈɕelʲɪ] and се́ли (séli, “sat down (pl.)”) [ˈsʲelʲɪ].

My understanding is that [ɕ] is effectively synonymous with [ʃʲ]; no language contrasts them, and it isn't even clear what the putative difference between them could be.

That sounds about right. I've never seen it described like that though, I've only seen [ɕ] described as [ʂʲ], but [ʃʲ] makes a lot more sense.

Yeah, I realize now that I should have been asking about a distinction between [ʃʲ] and [ɕ], thanks.
