Elle vont à l'extérieur du magasin.

Can this be a way to say, "They are going outside the store/shop"?

Since you have a plural verb, you must have a plural subject. Elle should be Elles

Oops...that's a typo. But other than that is it fine?

Yes. It looks ok to me.

Yes, your translation is correct. The sentence "Elles vont à l'extérieur du magasin" translates to "They are going outside the store/shop." Here's the breakdown of the translation:

- "Elles" means "they," referring to a group of females.
- "Vont" is the third person plural form of the verb "aller," which means "to go."
- "À l'extérieur" means "outside."
- "Du magasin" means "of the store/shop."

To arrive at this translation, you can break down the sentence piece by piece. Here's how:

1. Identify the subject: "Elles" (they).
2. Identify the verb: "vont" (are going).
3. Identify the prepositional phrase: "à l'extérieur du magasin" (outside the store/shop).
4. Combine all the parts to get the translation: "They are going outside the store/shop."

Remember that translation can sometimes involve considering the context and idiomatic expressions to ensure the most accurate interpretation.
