Arabic Inflecting the verb for the passive voice
The previous section outlined the steps of passive transformation without dealing
with step 3: “Inflect the verb for the passive voice”. This is done by changing
the vowel quality of specific vowels in the verb. In other words, what distinguishes
the active from the passive is internal vocalization of the verb.
Passive vocalization of the perfect tense verb
For the perfect form of the verb, the following are the relevant vowels:
v0 = initial vowel, v1 = the ف vowel, v2 = the ع vowel
(Forms I, II, and III have no initial vowel v0.)
Passive vocalization of the perfect:
If present, vowel v0 has to be /u/
If present, vowel v1 has to be /u/
Vowel v2 has to be /i/
Vowel transformations to inflect active for passive
The following chart illustrates the vowel transformations necessary to inflect
active perfect tense verbs for the passive voice:

Generalizations about the perfect in the passive voice
If there is a v0, the vowel quality is /u/.
If there is a v1, the vowel quality is /u/.
The v2 vowel quality is /i/.
Rare passives for forms V and VI.
No passives for forms VII and IX because they are reflexive in meaning.
