Note. Although ed in the past tense and participle is thus blended with the last syllable of the verb, yet when a noun is formed by adding ness to such participles the ed becomes a distinct syllable. Thus blesseded may be pronounced in one syllable; but bles-sed-ness, must be in three.
9. Verbs ending in ay, oy, ow, ew and ey, have regular de- rivatives in ed and ing.
ar-ray, ar-rayed, ar-ray-ing; al-lay, al-layed, al-lay-ing; pray, prayed, pray-ing; stay, stayed, stay-ing; de-lay, de-layed, de-lay-ing; al-loy, al-loyed, al-loy-ing; em- ploy, em-ployed, em-ploy-ing; de-stroy, de-stroyed, de-stroy-ing, an-noy, an-noyed, an-noy-ing; en-dow, en-dowed, en-dow-ing; re-new, re-newed, re-new-ing; con-vey, con-veyed, con-vey-ing; fol-low, fol-lowed, fol-low-ing; be-stow, be-stowed, be-stow-ing; con-voy, con-voyed, con-voy-ing; fol-low, fol-lowed, fol-low- ing; be-stow, be-stowed, be-stow-ing; con-voy, con- voyed, con-voy-ing.
