Additional rules to be applied are grouped by Typology. They can be viewed in the table above using the Typology selector.

Every verb is subject to the set of rules named General having a number of spelling rules as well as rules related to Form IX. A verb's typology determines which set of rules is to be applied. For example: a verb of typology Hollow is subject to the set of rules for typology Hollow, etcetera. There is no single set of rules for verb typologies Doubly Weak and Mixed. For these verb Typologies the sets of rules are applied of all constituent Typologies of that Doubly Weak or Mixed verb.

The set of rules named Special is applied exclusively to the verb with root (r, ', y) and Forms I-aa and IV.

The Hamza Seat Rules table above is used to determine a hamza's seat. Along the left hand side vertically it displays the character(s) preceding the hamza. Along the upper side horizontally it shows the character(s) following the hamza. Once these preceding and following characters are known the hamza seat can be simply read from the table at the intersection point of the row and column.

In determining the characters preceding the hamza 'y+sukūn' takes precedence over 'sukūn'. Similarly, in determining the characters following the hamza 'a+alif' takes precedence over 'a'. If a hamza carries 'shadda' then this 'shadda' is ignored in the process of determining the characters following the hamza.

A 'none' preceding the hamza indicates the hamza is the first character of a word. Similary, 'none' following the hamza indicates that the hamza is in final position.

If for example there is 'alif' preceding the hamza (row 6) and there is 'i' following the hamza (col 3), the point of intersection of this row and column shows the hamza seat as a yā'. Where applicable these rules are referred to as Hamza rules. They are displayed in the format (row,col): (6,3) in the example.
