Learn Spanish (Latin America): ¿Ustedes ven los animales?

The singular word is animal, which ends in a consonant (the letter l). In Spanish, when a noun ends in a consonant, you make it plural by adding -es. If it ended in a vowel (like perro), you would just add -s to make perros.

Where is the word for "Do" in this question?

Spanish doesn't use helper words like "do" or "does" to make questions. Instead, you just use the normal sentence order (Ustedes ven meaning "You see") and wrap it in question marks (¿ ?) to show you are asking a question.

Why do we use ven with ustedes?

Ustedes means "you" when talking to more than one person (like "you all" or "you guys"). In Latin American Spanish, ustedes always shares the exact same verb endings as "they". So, just like you would say Ellos ven (They see), you say Ustedes ven (You all see).

Why is it los animales instead of el animales?
