Learn Spanish (Spain): Ellas trabajan en el restaurante hoy.

In Spanish, the preposition en is the go-to word for location. It covers 'in', 'on', and 'at' all at once! You don't need a separate word to say they work inside the building; en el restaurante handles it perfectly.

Why does the sentence use Ellas instead of Ellos for 'They'?

Ellas specifically means a group of only females. If the group working at the restaurant was all male, or a mix of males and females, you would use Ellos instead.

How do we know the verb trabajan matches Ellas?

Regular verbs ending in -ar, like trabajar (to work), drop the -ar and add -an when talking about 'they' (ellos or ellas) or 'you all' (ustedes).

Could I put hoy at the beginning of the sentence instead of the end?

Yes! Time words like hoy (today) are quite flexible in Spanish. You could say Hoy ellas trabajan en el restaurante and it is perfectly natural.
