How do you make mochila a plural noun?

The word "mochila" is already plural in Spanish. It's a bit tricky because in English, the word "mochila" sounds similar to "mochila" (which is singular), but in Spanish, it's already plural.

Here's why:

* "Mochila" in Spanish is a feminine noun, ending in "-a." This ending indicates the plural form.

* The singular form is "mochil"

So, if you want to talk about more than one backpack, you would still say "mochilas."
