Quadrilateral Bare (Rubaa'i Mujarrad) - Bab 1: Fa'lalah (Ba'tharah)

1. From Trilateral to Quadrilateral

So far, the course has mainly dealt with verbs built from 3 original root letters.
A Rubaa'i verb has exactly 4 original root letters.
Like triliteral verbs, quadrilateral verbs are divided into two broad types:
1. Mujarrad — no added letters.
2. Mazeed Feeh — one or more added letters.

2. Rubaa'i Mujarrad Has One Door

In this course, Rubaa'i Mujarrad is taught through one bare door.
Its basic past-tense pattern is فَعْلَلَ.
The example is بَعْثَرَ.
All 4 letters in this example belong to the original root.

3. Root and Masdar

The original root letters of بَعْثَرَ are ب، ع، ث، ر.
Its verbal noun is بَعْثَرَةٌ.
Its meaning here is to scatter, overturn, or throw into disorder.

4. Complete Sarf-e-Sagheer

Recite the complete Sarf-e-Sagheer together:
بَعْثَرَ يُبَعْثِرُ بَعْثَرَةً فَهُوَ مُبَعْثِرٌ وَبُعْثِرَ يُبَعْثَرُ بَعْثَرَةً فَهُوَ مُبَعْثَرٌ الأَمْرُ مِنْهُ بَعْثِرْ وَالنَّهْيُ عَنْهُ لَا تُبَعْثِرْ
This paradigm includes active and passive verbs, Masdar, Ism Fa'il, Ism Maf'ool, imperative, and prohibitive.
