Like all Spanish adjectives, 'decidido' must match the person or thing it describes in both gender and number: 'Ella es decidida' (She is determined) vs. 'Ellos son decididos' (They are determined).

Describing Character
Use 'decidido' primarily with the verb 'ser' (to be) when describing someone's fixed personality trait or state of strong will.

💡 Grammar Points
The Perfect Tenses (Haber)
When used with the verb 'haber' (e.g., 'he,' 'has,' 'ha'), 'decidido' never changes its form. It always stays 'decidido', regardless of who is speaking or the object of the verb.
Passive Voice and Results (Ser/Estar)
When used with 'ser' (for passive voice) or 'estar' (for a resulting state), 'decidido' acts like an adjective and MUST change gender and number: 'La hora está decidida' (The time is decided).
❌ Common Pitfalls
Changing Gender with 'Haber'
Mistake: "Hemos decidida la cena."
Correction: Hemos decidido la cena. (The participle only changes when used with 'ser' or 'estar', not 'haber'.)

Frequently Asked Questions
Is 'decidido' always an adjective?
Not always. While it functions as a descriptive adjective meaning 'determined' (Ella es decidida), its most frequent use is as the past participle of the verb 'decidir' (to decide). This fixed form is essential for creating perfect tenses like 'He decidido' (I have decided).
Why does 'decidido' sometimes change to 'decidida' or 'decididos' and sometimes stay the same?
It changes when it acts as a true adjective or describes a resulting state (with 'ser' or 'estar'). It remains 'decidido' when used with the helping verb 'haber' to form compound tenses (like 'ha decidido'), regardless of the noun or pronoun.
