If
then
Example:
| دُلُوْوٌ | → | دُلِيٌّ |
Note:
The fāʾ kalimah may also be given a kasrah.
Example:
| دُلُوْوٌ | → | دِلِيٌّ |
When a maṣdar of the pattern faʿlūlah has a wāw as its ʿayn kalimah, the wāw is changed to a yāʾ.
When a plural on the scale of فُعْلٌ, or a feminine adjective on the scale of فُعْلى, has yāʾ as its ʿayn kalimah, the preceding letter takes a kasrah.
When wāw and yāʾ combine in one word under set conditions, the wāw becomes yāʾ and the two merge with tashdīd.
When a و or ي follows a ḍammah in the lām of an ism, the ḍammah shifts to a kasrah and the weak letter is dropped after the two sākins meet.
