The additional conjugational rules are grouped by Typology.
All Typology rule sets can be viewed in the table above using the Typology selector.

Every verb is subject to the set named General that has a number of spelling rules as well as rules related to Form IX.
If a verb is of Typology A then it is subject to Typology rules A.
There is no set of rules for verb typologies Doubly Weak and Mixed. For these verb Typologies the Typology rules are applied of all constituent Typologies of that Doubly Weak or Mixed verb.

Among the Typologies there is one named Special which is applied exclusively to the verb with root (r, ', y) and Forms I-aa and IV.

The Hamza chair table above is used to determine the hamza chair. Along the vertical axis it displays the character(s) preceding the hamza. Along the horizontal axis it shows the character(s) following the hamza. Once these preceding and following characters are known the hamza chair can be read from the table at the intersection point of the row and column.

If for example there is an alif preceding the hamza (row 6) and there is a vowel i following the hamza (col 3), the point of intersection of this row and column shows the chair as a yā'. These rows and columns are referred to on RESULTS in the View called Hamza rules for Typology=Hamzated. They are displayed in the format (row,col).

A 'none' preceding the hamza indicates the hamza is at the beginning of the verbal form. Similary, 'none' following the hamza indicates that after the hamza there is at most one character.
