Learn Spanish (Spain): Estamos comprando la fruta y las verduras. - We are buying the fruit and the vegetables.

Estamos comprando means "we are buying" right now, at this exact moment. This is made by combining estamos (we are) with comprando (the "-ing" form of comprar). If you say compramos, it can mean "we buy" as a general habit or "we are buying", but estamos comprando emphasizes that it is happening right now.

Where is the word for "we" in this sentence?

In Spanish, the word for "we" (nosotros or nosotras) is usually left out because the verb estamos already tells us exactly who is doing the action. You only need to include it if you want to add special emphasis.

Why is la fruta singular but las verduras plural?

In Spanish, la fruta is often used as a singular noun when talking about fruit as a category (just like in English, we usually say "fruit", not "fruits"). However, vegetables (las verduras) are typically referred to in the plural.

How do I make the "-ing" form for other verbs, like comprando?

For verbs that end in "-ar" like comprar (to buy), you drop the "-ar" and add -ando. That gives you comprando (buying). If the verb ends in "-er" or "-ir", you usually add -iendo instead.
