Irregular verbs in general take the mood-signs
regularly. Nonetheless, defective verbs are irregular when it comes to
mood-signs, and hollow verbs require one alteration when they are in
the jussive mood. It should be remembered that the plural feminine
conjugations are always built words and will not undergo mood inflection.
All verbs will have regular signs except for
the defective and hollow verbs.
Defective Verbs
Defective verbs
النَاْقِصُ
are verbs whose last original letter is a weak
letter. The imperfective of a defective root will end in a weak letter.
Altering the mood sign will not be an issue for the "five verbs"
الأَفْعَاْلُ
الخَمْسَة , because
it is
simply either to keep or remove the last
noon
ن
. The problem would be, however, when adding a short vowel mood sign (a
move) to a long vowel final letter, which is the case for the rest of the
verbs other than the five verbs.

-u--
---ُ
يَدْعُ

-i--
---ِ
يَأْتِ
(he) come
The long vowels were omitted
and replaced with the corresponding short vowel.
Example:
(
أَتَىْ'ataa
= came (to)). The root is :
أ ت ي
T Y '
Hollow verbs
الأَجْوَفُ
are verbs that have a weak letter as the
second original letter. Hollow verbs act perfectly normal in terms of moodsigns. However, there is one change that should be applied to these
verbs when they are in the jussive mood; the middle weak letter must be
omitted.
Examples:
Jussive
Indicative
yaqul
يَقُلْ
yaqool(u)
يَقُوْلُ
yabi"
يَبِعْ
yabee"(u)
يَبِيْعُ
yanam
يَنَمْ
yanaam(u)
يَنَاْمُ
However, this change will spare the "five verbs." These will retain the middle weak
letter.
Example:
(
كَاْنَ
kaan(a)
= was). The root is :
ك و ن
K
W N
