In Arabic; the verb itself has the subject. As it’s expressed in a prefix = (letter at the beginning)/ or a prefix and a suffix = (letter/s at the end).
This means that, all verbs in the Arabic language are regular! You don’t need to change the root of the verb at any tense (past, present and future).
So, to express (I eat/ or I’m eating): (‘anaa ‘a’kul), you can simply say: (آكل)(‘a’kul) without a pronoun, as the verb itself tells about it.
