Irregular Subjective Nouns

ٍSubjective nouns can be tricky to use and understand correctly. They imply slightly different meanings in different situations and for some verbs they can't be use in the regular form.

We will try to list the forms of the subject nouns and explain their meaning

• In the process of doing the action

The most famous form
I'm going to school    انا رايح المدرسة
I want an apple    انا عايز تفاحة

• Action that will happen in the near future (using subject noun for the near future implies certainty)

I'm sorry I can't come with you because I'm going out tonight
انا اسف مش هقدر اجي معاكم علشان انا خارج بالليل

• Strictly the subject (the doer)

It can refer to the doer of an action or in many cases occupation

The writer   كاتب

• Just finished the action but its consequences are still in the present 

I arrive at home, my mother is done cooking, I can ask her:
what did you cook today?      انتِ طابخة ايه النهاردة؟

The confusion here is that not all subjective nouns can be used in those forms. You will have to learn which subjective nouns are used in which form and what they imply.

Note that you can use the subjective nouns in the past continuous tense by adding "was"
I was walking to work when I met him
انا كنت ماشي للشغل لما قابلته
