If I would like to say:

"Is your brother at home?" would it be correct to say:
est-il à la maison, votre frère?
or
votre frère, est-il à la maison?

Are your children in school"
Sont-ils à l'école, vos enfants?

Thank you

ton/votre frère est-il à la maison?

est-ce que ton/votre frère est à la maison?

and "vos enfants sont-ils à l'école OR

Est-ce que vos enfants sont à l'école. Do you remember the 4 ways to ask a question that I gave you earlier?

Mme

P.S. The first sentence you wrote is as awkward as "Is he at home, your brother?"

Mme

thank you!

thank you very much!

Both of the given sentences are correct but have slightly different word orders. Here is the breakdown of each sentence:

1. "Is your brother at home?"
- "Est-il à la maison, votre frère?" (Is he at home, your brother?)
- In this sentence, the subject "il" (he) is placed before the verb "est" (is) for a more formal inquiry.

- "Votre frère, est-il à la maison?" (Your brother, is he at home?)
- In this sentence, the subject "votre frère" (your brother) is placed before the verb "est" (is) for a more informal inquiry.

Both forms are grammatically correct in French. The choice between them depends on the level of formality or personal preference.

2. "Are your children in school?"
- "Sont-ils à l'école, vos enfants?" (Are they in school, your children?)
- This sentence follows a similar pattern as the first sentence, where the subject "ils" (they) is placed before the verb "sont" (are) for a more formal inquiry.

Again, this sentence can be rearranged as:
- "Vos enfants, sont-ils à l'école?" (Your children, are they in school?)
- In this case, the subject "vos enfants" (your children) is placed before the verb "sont" (are) for a more informal inquiry.

Remember, both forms are correct, and the choice depends on the desired level of formality or personal preference.
