Conjugation of Irregular Verbs
For description of irregular verb types,
you may go here
1) Doubled Verbs
Doubled verbs are
verbs that end with ashadda(t),
which indicates doubled consonants
without a vowel in between.
The imperfective doubled
verbs will need to be restored to their original forms in the feminine
plural conjugations.
A point we made when we
defined the doubled verbs is that there are two types of them;
ones that have an omitted short
vowel from between the doubled letters (-CvCvC → -CvCC, most of the verb forms) and ones that have a
displaced-back short vowel (-CCvC → -CvCC, only forms I, IV, X & QIV in
the imperfective).
This distinction is important in the imperfective because this vowel we are
talking about is the changeable green short
vowel of the imperfective structure.
For the doubled verbs with
an omitted short vowel, there will not be a green short
vowel in the imperfective because it is omitted. It will appear only when
we restore the verbs to their original forms in the feminine plural
conjugations.
For the doubled verbs with
a displaced-back short vowel, there will be a green short
vowel but it will be displaced back in the structure. It will move
back to its original position only when we restore the verb to its
original form in the feminine plural conjugations.
Example, the form VIII
verb:
Original Form
Doubled Verb
اِشْتَدَدَ
اِشْتَدَّ
'ishtadad(a)
'ishtadd(a)
(He) intensified (intr.)
A form VIII verb is a Ya-i
verb. However, when this verb is
turned into an imperfective, there will be no chance for the green short
vowel to show itself because it is deleted:
Original

Doubled Verb
يَشْتَدِدُ
يَشْتَدُّ
yashtadid(u)

(They masc.) intensify
yashtaddoon(a)
يَشْتَدُّوْنَ
(They fem.) intensify
yashtadidn(a)
يَشْتَدِدْنَ
The verb stem is restored
to its original form in the feminine plural conjugations to prevent the
formation of three-consonant clusters (ddn).
This will be the
conjugation for all the forms that can be doubled verbs except forms I, IV, X & QIV.
For these, the green vowel is displaced not deleted, so it will show up.
Example, a form IV verb:

The verb stem is restored
to its original form in the feminine plural conjugations.
►Form I Doubled Verbs
Perfective form I doubled verbs have an
omitted short vowel.
fa"al(a)
fa"il(a)
→
fa"l(a)
fa"ul(a)
However, if we were to omit the vowel in
the imperfective, we would get the following:
yaf"al(u)
yaf"il(u)
→
yaf"l(u)
yaf"ul(u)
Because the
a
between the first two root-letters is deleted
in the imperfective, we would get yaf"l(u)
which contains a three-consonant cluster that is unpronounceable.
Therefore, they had to keep the green short
vowel in these verbs, but since the resultant structure contained
-CCvC, like
forms
IV, X & QIV,
they treated it in a similar manner and displaced the green vowel back
-CCvC → -CvCC.
yaf"al(u)
yafa"l(u)
yaf"il(u)
→
yafi"l(u)
yaf"ul(u)
yafu"l(u)
Example, the verb:

عَدَدَ

The verb stem is restored
to its original form in the feminine plural conjugations.
Thus, form I doubled verbs
change from verbs with an omitted vowel in the perfective to verbs with a
displaced-back vowel in the imperfective.
Note that imperfective
form I doubled verbs are mostly
u

verbs and most of these are classical verbs.

Mithaalverbs
are verbs whose first original letter is a weak letter.
These verbs
conjugate regularly in the perfective. In the imperfective, they conjugate
regularly in all the forms but
forms I & IV.
In these two forms, the conjugation can be regular or irregular depending
on whether
the first original letter isy
or
