When is a pronoun needed before a verb in Arabic?

 In Arabic, personal pronouns are often included before the verb to indicate the subject of the sentence, especially in spoken Arabic. However, the use of the pronoun is not always necessary because the verb itself often indicates the subject.

For example, the verb "أتكلم" (atakallam) in the sentence "نعم، أتكلم العربية" (Yes, I speak Arabic) is already conjugated to indicate that the subject is the first person singular "I". Therefore, it is not necessary to include the pronoun "أنا" (ana) before the verb.

However, in some cases, the pronoun is used for emphasis or clarification, especially when the subject is not clear from the context. For example, if someone asks "من يتكلم العربية؟" (Who speaks Arabic?), the response could be "أنا أتكلم العربية" (I speak Arabic), where the pronoun "أنا" (ana) is included for emphasis and to indicate clearly that the speaker is the one who speaks Arabic.
