Questions & Answers about أين هو هذا الدرس في الكتاب؟
Why does the sentence start with أين? Is that normal word order in Arabic?
Yes. أين (where) is an interrogative word, and it typically comes at the beginning of the question in Modern Standard Arabic (MSA).
So أين ...؟ = Where ...? is the standard way to form a where-question.
What is the role of هو here? Do I have to include it?
هو is the pronoun he/it and here it functions like a copula (roughly like is) in a nominal sentence. In MSA, you can say:
- أين هذا الدرس في الكتاب؟ (often acceptable, especially in less formal style)
- أين هو هذا الدرس في الكتاب؟ (very common and clear)
Including هو can make the sentence feel a bit more explicit: Where is this lesson in the book?
Why is it هو and not هي?
Because الدرس (lesson) is masculine in Arabic. The pronoun used to refer to it is therefore هو.
If the noun were feminine (e.g., الصفحة the page), you might use هي:
- أين هي هذه الصفحة في الكتاب؟
