How to make words from a root word

Today we'll learn to make 10 words from a root word.
If you learn these 10 rules, you will be able to make 10 words from any root word you know.
If فعل is a root then: فاعل is the one who does that فعل
فاعلة (fa'ila) Is the female who does that فعل
مفعول (Maf'ool) is the male on whom the فعل is done
مفعولة (Maf'oolah) is the female on whom the فعل is done
فعلت (Fa'lat) is the noun of that فعل
 أفعال (Af'aal) is the plural of that فعل
 یفعل - (Yaf'al) means "He does / would do" that فعل
 فعيل (Fa'eel) somebody who is too much of فعل. Superlative degree.
 فاعلين (Fa'ileen) plural of فاعل
 تفعيل (Taf'eel) the product of the process of that فعل

Now let's take an example of a root and apply these rules on it.
Root Word ولد (wa la da)
Closest english word to describe ولد is "birth". I am applying the rules stated above in the same order.
 1۔ والد
2۔ والدة
3۔ مولود (نو مولود)
4۔ **
5۔ ولدت (ولادت)
6۔ اولاد
7۔ **
8۔ وليد (name)
9۔ والدين
10۔ **
Molood مولود means the born
Nau molood bacha نو مولود بچہ - Newly born child
ولادت birth
Waleed وليد means "very young male child"
More Urdu words from this root are: ولدیت (waldeeyat) and میلاد (milaad)
Literally meaning "Time of birth" ... Meaning birthday. ميلاد النبى

Surah Fatiha (lesson 9)

 بسم الله الرحمن الرحيم
Today's word is
Wa-La-zZa'leen
ولاالضالين
"Wa" means "And"
"La" means "Not"
Notice an "AL" before Za'aleen.. which is silent when reading the word. Despite being silent it holds its meaning "The" (that's the Arabic rule). Lastly the main word Zaa'leen ضالين comes from the root Za La La  ضلل
The closest Urdu word is Zaleel ضليل having the same meaning as the original root.
The root ZaLaLa ضلل means to get lost, to get off track and then trying to find your way back but all efforts go into waste. This is called Zaleel hona. The best analogy which experts give to explain this root is when a traveller gets lost in dessert, and makes an effort to find his way, but this effort exhausts his energy, he dehydrates himself, and bring upon him his own death.
That is the truest essence of Zaleel hona. The grammar to learn here is how you make a plural from singular. For Example: 
Muhajir's plural can be made in two ways Muhajiroon and Muhajireen
Momin -> Mominoon & Momineen
So whenever you see an "een" ين or "oon" ون at the end of a word then know that it is a plural.
Hence Al-Za'leen are all those specific people who got lost or got off track.
Who were the Zalleen? The Quran tells the stories of all those people in detail.

Today we are done with the first chapter of the Book. We discussed around 22 Arabic words and identified their roots. For every root we discussed around 3-4 other Arabic / Urdu words belonging to the same root to understand the gist the root itself. So in total you would know 80-90 Arabic words already. Mashallah.
May Allah help us retain this knowledge.
