0) Although the grave accent marked a lower pitch or lack of pitch in earlier Greek, in the Koine period when accents had moved away from pitch to syllable stress, did the grave denote a LACK of stress or did it mark stress just like the acute and circumflex accents? In other words, by the Koine period, did ALL the accents denote stress or was it:[*]acute = stress[*]circumflex = stress[*]grave = no stress?  These question seems important to figure especially when it comes to phrases where you have a bunch of words one by one that have grave accents--it sounds very monotone and awkward. I'm finding that sentence flow seems smoother when the grave accents are stressed.  0) Are words with one syllable such as δέ, καί, τοῦ, τῷ, τῇ, ἤ, etc. stressed in context? After all, the purpose of stressing a syllable is so that particular syllable is highlighted from the rest of the syllables of that word, but obviously this would be redundant if a word has only one syllable.
