💡 Grammar Points
Adjective Agreement
Since 'abiertas' ends in '-as', it must describe feminine things that are plural (more than one), like 'las ventanas' (the windows) or 'las tiendas' (the stores).
Ser vs. Estar
When describing a temporary state, use 'estar' (Las puertas están abiertas = The doors are currently open). When describing a permanent characteristic, use 'ser' (Las personas son abiertas = The people are open-minded).
❌ Common Pitfalls
Forgetting the Plural
Mistake: "La puerta está abierta."
Correction: La puerta está abierta. (If you are talking about one feminine door, you must use the singular form 'abierta').

Frequently Asked Questions
Why is 'abiertas' considered irregular?
It is irregular because its parent verb, 'abrir' (to open), forms its past participle ('abierto') in a way that doesn't follow the standard '-ido' ending for '-ir' verbs. The feminine plural form 'abiertas' follows that irregular pattern.
How do I know if I should use 'ser' or 'estar' with 'abiertas'?
Use 'estar' when describing a temporary state (The windows *are* open now: 'Las ventanas están abiertas'). Use 'ser' when describing a fundamental characteristic (The discussions *are* open-ended: 'Las discusiones son abiertas').
