(Subjective Noun) أسم الفاعل

Subjective nouns are used frequently in Egyptian. They denote a state. If you think in English tenses, subjective nouns are used in the same manner of continuous tense. I believe it is useful to put it in contrast to the tenses used in Egyptian.

• I went to school     انا روحت المدرسة  (past tense)
• I go to school      انا بروح المدرسة (present tense)

This tense in Egyptian gives the meaning of a habit. It implies that you go to school everyday. 

• I will go to school   انا هروح المدرسة (future tense)
• I'm going to school  انا رايح المدرسة (continuous tense)

The subjective noun here gives the meaning that the subject (me) is in the process of doing the verb. In that sense, it is really related to both the verb (the action) and the doer (the subject). 

For example you can refer to the people going to school (similar to English)

• All the kids going to school are happy   كل العيال اللي رايحين المدرسة مبسوطين
