Dear hist-linguists,<br><br>I remember reading somewhere that the velar nasal consonant /ng/ tends to be less stable diachronically than the more common nasals /m/ and /n/, but I can't recall exactly where I found that piece of information. I would really appreciate any suggestions on where to find information on this topic, as well as any examples illustrating the diachronic behavior of this consonant in specific language families. [In the Macro-Jê stock, for instance, while reflexes of Proto-Jê *m and *n tend to be preserved as such in most related languages, *ng occurs as /k/ in Central Jê (thus merging with reflexes of Proto-Jê *k), zero in Jabuti, etc.]<br>
<br>Thanks in advance,<br><br>Eduardo
