It is well known that consonant lenition or weakening tends to be far more common cross-linguistically than the opposite process called fortition or strengthening. Now, some languages have been considered as having undergone the historical change of affricates to plosives. Here's a list of examples I've been able to collect so far:
- Proto-Samoyedic */t͡ʃ/ → Kamassian /t/
- Proto-Yeniseian */t͡ʃ/ → Proto-Ket-Yugh */t/
- Proto-Yeniseian */d͡ʒ/ → Proto-Ket-Yugh */d/
Thus, my question is:
What other languages can be shown to have undergone similar affricate-to-plosive fortition?
And, quite naturally, another related question arises here: Do the languages with affricate fortition cluster areally? At least, Yeniseian and Samoyedic have been neighbours for some time, and their proximity might explain why some of them share this peculiar change.
Contrary to what some, though not all, Yeniseists say, namely that Yeniseian has been rather immune to (mainly lexical) influences from its neighbours, areal patterning like this (if areal indeed), could suggest possible further directions for future research. In fact, the two groups seem to share other fortition paths as well: fricative → plosive (with affricate as a possible intermediary step). But for the time being, I'd really like to know what else one could find about affricate-to-plosive changes world-wide.
I'll be extremely grateful for any other examples from some other languages, or references to relevant literature discussing them. Many thanks in advance!
