Learn Hardcore Spanish (Latin America): Mis amigos llevan agua al parque cada semana. - My friends bring water to the park every week.

In Spanish, when you talk about a substance in a general, non-specified amount (a “mass noun”), you usually omit the article. Here agua (“water”) is uncountable and indefinite, so no el or la appears. If you wanted to refer to a specific water bottle, you might say el agua or una botella de agua, but for “some water” in general, you leave out the article.

What does llevan mean here, and why not traen?

Llevar means “to take” or “to carry (away to another place),” whereas traer means “to bring” (toward the speaker’s current location). Since the action is moving water from some origin toward the park (not toward where the speaker is right now), Spanish uses llevar. The form llevan is simply the present‐tense, third person plural (“they carry/take”).

Why do we say al parque instead of a el parque?

In Spanish you combine the preposition a (“to”) with the masculine article el (“the”) into a single word: al = a + el. So al parque literally means “to the park.”

What does cada semana mean, and why not cada las semanas or todos los semanas?

Cada means “each” or “every” and is always followed by a singular noun: cada semana = “every week.” If you want a plural form, you must switch strategies: todas las semanas (“all the weeks” or “every week”) is correct, but todos los semanas is wrong because todos would agree with a masculine noun (todos los días, for example).

Why is it mis amigos instead of los amigos míos?

Mis amigos uses a possessive adjective (mis) before the noun and is the most straightforward way to say “my friends.” Los amigos míos is also correct but is less common in everyday speech and can add a slight nuance of emphasis or formality (“the friends of mine”).

Could we move cada semana to the front of the sentence? Does word order matter?

Yes. You can say Cada semana, mis amigos llevan agua al parque to put emphasis on every week. Spanish is flexible, but the neutral order is Subject-Verb-Object with time and place either at the beginning for emphasis or at the end for a more standard rhythm.

Why use llevar agua if they want to drink it? Wouldn’t they use tomar or traer?

These verbs have different meanings:

Llevar = to take/carry something to a place (“take water to the park”).
Traer = to bring something toward where the speaker/listener is.
Tomar = to drink or to take (as in “to have a drink of water”).
In this sentence the emphasis is on transporting water to the park, not on drinking it or bringing it to the speaker.
