Learn Spanish (Latin America): ¿Por qué no visitamos la playa los domingos?

In Spanish, you don't use a word like 'on' before days of the week. Instead, you just use the definite article (el for a single day, los for multiple days). So, los domingos translates perfectly to 'on Sundays'.

How do you make days of the week plural?

For days that end in a vowel, like domingo (Sunday), you just add an -s to make it domingos. But remember, for weekdays that already end in an -s (like lunes or martes), the day word itself doesn't change. You only change the article from el to los (for example, los lunes).

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

It's built right into the verb! Visitamos is the 'we' form of visitar (to visit). Because the -amos ending already tells us who is doing the action, the pronoun nosotros (we) is usually left out to sound more natural.

Why is por qué written as two words with an accent mark here?

When it means 'why' in a question, it is always written as two separate words with an accent on the e: por qué. If you see it written as one word with no accent (porque), it means 'because'.
