Questions & Answers about Tú ves unos perros pequeños aquí.
Why do we use unos here instead of los?
unos is a plural indefinite article, which translates to "some" in English. We use it here because we are talking about "some" small dogs in general. If we wanted to say "the small dogs" (specific dogs we already know about), we would use the definite article los.
Why is pequeños placed after perros?
Why does pequeños end in -os?
Adjectives in Spanish have to match the noun they describe in both gender (masculine or feminine) and number (singular or plural). Because perros is masculine and plural (more than one), the word for small (pequeño) must also change to its masculine plural form: pequeños. Notice how unos, perros, and pequeños all perfectly match with that -os ending!
Do I have to include Tú at the beginning of the sentence?
