Question

Does (Old) Armenian have examples of ձ / զ (dz / z) alteration?

Answer 1

I can’t find one, but it is hard to say that it never ever happened, without an exhaustive search.

(“Absence of evidence is not evidence of absence.”)

Etymologically ձ evolved from a few different sounds, maybe depending on the position. Note that the modern pronunciation is more like dz, even though linguists use j.

I found an example of alteration with ծ (ts one letter) and with դզ (dz two letters).

My gut says ձ and զ are relatively distinct, and that we may not know the ancient pronunciation of ձ, but that it is more like a palatalisation of or cluster with initial դ.
