الصَّرْفُ
Divisions of حُرُوف العِلَّة
{ حُرُوف العِلَّة are the 3 weak letters: (ا) "alif", (و) "wāw", & (ي) "yā’"}
These verbs are called مُعْتَل - i.e. one of the three ف al-Kalimah, ع al-Kalimah or ل al-Kalimah will have a (ا), (و) or (ي).
{* There are 4 divisions but we will be taking only 3.}
1.
First division is when the حُرُوف
العِلَّة is in the place of ف al-kalimah.
E.g. وَعَدَ and يَسَرَ
In وَعَدَ - This verb
has حُرُوف
العِلَّة in its root. The ' ف ' al-kalimah of this word has a و (waaw).
In the case of
وَعَدَ
and يَسَرَ we don't
have to search for the root letters as the root letters are clear. It will
always be a و or a ي and never an Alif in
the place of ف al-kalimah. The reason being the Alif
is always a sukoon and it cannot be pronounced.
2.
Second division is when the حُرُوف
العِلَّة is in the place of ع al-kalimah.
E.g. صَاْمَ and باْعَ
The root letters are not
clear in these two words صَاْمَ and باْعَ because of the presence of Alif in
these words.
