When two wāws meet at the end of the scale فُعُوْلٌ, both become a yāʾ with shaddah and the preceding ḍammah turns to a kasrah.
When a maṣdar of the pattern faʿlūlah has a wāw as its ʿayn kalimah, the wāw is changed to a yāʾ.
When a wāw sits as the ʿayn kalimah of a maṣdar after a kasrah, or in a plural, it converts to a yāʾ if its verb takes the rules of taʿlīl.
When a plural on the scale of فُعْلٌ or فُعْلى has yāʾ as its ʿayn kalimah, the preceding letter takes a kasrah.
