Sound Change Term Question

[2+3 clusivity]

Is there a term for a sound change of the following pattern --

/-VASV-/ --> /-VASAV-/; and some nonse examples, /alga, dijda, albəm/ -> /algla, dijdja, albləm/

A = approximant; S = Stop; V = Vowel

Inserting a sound is called epenthesis.

I don't get the pattern, though. I don't see what the (phonetic) motivation is for epenthesizing either [l] or [j], and anyway, "approximant" is a pretty vague term since it can mean stuff like lateral approximants or just glides like [j].

Were it just VASV > VSAV it'd be metathesis, which is a fairly common change, but as it stands I can neither think of an appropriate name for it nor think of a natural example of it. It's very distinctive, at any rate.

I don't have any real problem with the approximant category in this case. If the sound change applies to all approximants, whether glide or liquid, then this is an appropriate way to describe it.

It's common but AFAIK usually not a regular sound change that applies across the board.

Ohh, wait a minute. So you repeat the approximant. OK. That's what I didn't realize until just now. I feel like there must be a better way of expressing this with this notation, like αA or something (so something like /-VASV-/ -> /-VASαAV-/?).

The point is the sequence C₁C₂ turns into C₁C₂C₁ intervocalically.

I don't know, I would either call it a specific type of an epenthesis (where a consonant cluster gets separated from a vowel by introducing one more consonant), or—if I were to invent a new term—I would call it something like “perithesis” (Greek for “putting sth around sth”).

Yeah, sorry, my notation is not great. Pole and Vijay hit on the pattern. An approximant -- here, /j, w, l, etc./ is repeated following a stop.

Epenthesis seemed awkward to me given that it usually breaks CC or VV cluster.

"Perithesis" ... ha! That's good. Thanks folks.

It is a very common sporadic sound change, but there are some cases of it being systematic. For example, Common Slavic had systematic metathesis of coda liquid consonants with the preceding vowel.

It's supposed to have happened systematically in Romani as well, but I'm skeptical in that particular case at least.

Avestan has regressive "perithesis" of /j/, but this probably works thru palatalization: Cj > Cʲj > jCj. The same mechanism might be difficult to extend to liquids.
