Questions & Answers about Est-ce que tu voyages en Espagne ?
Why do we use en before Espagne instead of à or au?
The translation says 'to Spain', but doesn't en mean 'in'?
It means both! In French, the preposition you use for a country doesn't change based on motion. Whether you are traveling 'to' Spain or already living 'in' Spain, you use en Espagne.
Why is there an 's' at the end of voyages?
Because the subject is tu (the informal 'you'). For regular '-er' verbs like voyager, the tu form always ends in '-es', even though the 's' is silent.
I see 'are traveling' in the translation. Where is the word for 'are'?
French doesn't have an exact match for the English 'are doing' or 'am doing' forms. The simple present tense tu voyages covers both 'you travel' and 'you are traveling'.
What exactly does Est-ce que do at the beginning of this sentence?
It acts as a question marker. Putting est-ce que (which literally means 'is it that') at the start of a normal sentence turns it into a yes/no question without needing to change the word order.
