In this article, I explain an important but simple rule related to subject-verb concordance in Arabic. If the verb follows the subject, it must correspond to him in number and sex, z.B. but if the verb is in front of the subject, it corresponds only to the subject in sex, and it remains singular, z.B. in total, if the subject arrives according to the verb, it corresponds to him, both in sex and in number; But if he comes before that, he is in agreement with him in sex, but remains unique at all times. This rule is not influenced by the temporal form of the sentence, that is, it applies to any verb and subject, regardless of the form of the tense. Can you start the following sentences with the verb taking this rule into account? الطالبتان تدرسان في الجامعة. . . .
