Tonal and stress accents

[petegray]

Thank you, Jens for you posting on stress and tone accents.

You use the stress accents of some modern languages, such as Greek, to argue
that PIE must have had stress.   Does this argument necessarily follow?

(a) Isn't the old argument also possible, that the accent in Greek has
changed from pitch to stress? (and presumably therefore also possible in the
other languages that you mention)

(b) There are no indications of stress accent in Classical Greek, neither in
the grammarians, nor in what the accent does to the phonology, metre, or
anything else.   See W Sidney Allan Vox Graeca.
