I recently learned (in this forum) that natural classes of tones are posited based on the tendency of members of those classes to act together (that is, I suppose, to have the same effect based on a rule).
In the same way that [p, t, k, ch] act together in many languages, so too do some tones.
I guess this means that Rising tones may pattern with High Tones (but not the opposite) and Falling tones may pattern with Low tones (but not the opposite), but I'm just grasping at straws here.
I learn best from examples in real languages, but I have trouble finding a relatively easy example of natural classes of tones.
Can someone help me understand this a little better? I'm so close, but just struggle conceptualising. Thanks!
