💡 Grammar Points

Matching the Noun

Since 'abiertos' is an adjective, you must use it with masculine plural nouns (like 'libros' or 'negocios'). For feminine plural nouns (like 'puertas'), you must use 'abiertas'.

State vs. Action

We almost always use 'abiertos' with the verb 'estar' (to be) to describe the current state of something (e.g., 'Los libros están abiertos').

❌ Common Pitfalls

Using the wrong 'to be' verb

Mistake: "Los libros son abiertos."

Correction: Los libros están abiertos. ('Ser' describes what something *is* inherently, 'estar' describes its temporary state, like being open.)

⭐ Usage Tips

Irregular Participle

Remember that the base verb 'abrir' (to open) has an irregular past participle: 'abierto', not 'abrido'. All forms (abierto, abierta, abiertos, abiertas) follow this irregularity.

A person stands with arms open wide in a welcoming gesture, smiling gently while several colorful, distinct geometric shapes, representing new ideas, float toward them.
