Questions & Answers about Où est-ce que l'aigle vole ?
How does est-ce que fit into our lesson about c'est ... que emphasis?
Est-ce que is actually the question form of a cleft sentence! Just as you can say C'est là que l'aigle vole (It is there that the eagle flies), asking Où est-ce que l'aigle vole ? literally translates to "Where is it that the eagle flies?". It relies on the exact same grammatical mechanism you're currently studying.
Could I just use inversion here instead of est-ce que?
Yes, but with a noun subject like l'aigle, formal inversion gets a bit heavy. You would have to use complex inversion, which repeats the subject as a pronoun: Où l'aigle vole-t-il ?. Using est-ce que allows you to keep the simpler, standard subject-verb word order (l'aigle vole).
Is Où l'aigle vole ? acceptable without the est-ce que?
In casual spoken French, yes. You will often hear people drop the est-ce que and just say Où l'aigle vole ? or L'aigle vole où ?. However, Où est-ce que l'aigle vole ? is the standard, universally correct way to ask this question.
Doesn't the verb voler also mean something else?
Yes, voler means both "to fly" and "to steal". Context is key! Here, an eagle is obviously flying. But if you see a sentence like L'homme a volé mon sac, it means "The man stole my bag."
