Questions & Answers about Estas canciones son bonitas.
Why is it estas and not estos or esos?
Estas is a demonstrative adjective that means these and must agree with the noun in gender and number:
If the noun were masculine plural, you’d use estos (e.g. estos libros – these books).
Esos means those (a bit further away), not these, so it would change the meaning:
- estas canciones = these songs (near me)
- esas canciones = those songs (a bit further away)
How do I know that canciones is feminine?
The singular form is la canción (the song). Nouns ending in -ción are almost always feminine in Spanish:
- la canción → las canciones
- la nación → las naciones
- la decisión → las decisiones
So canción is feminine, and its plural canciones stays feminine, which is why you use estas and bonitas (both feminine plural) with it.
Why does bonitas end in -as and not -os or something else?
