reh-hees-TRAH-doh/rexisˈtɾa.ðo/

Examples

Agreement Rule
As an adjective, 'registrado' must match the thing it describes in both gender (masculine/feminine) and number (singular/plural): 'la casa registrada', 'los nombres registrados'.
How to Use Past Participles
'Registrado' is the part of the verb that never changes when you use it with the helping verb 'haber' to talk about completed actions: 'He registrado', 'Hemos registrado', 'Han registrado'. It always stays 'registrado' (or 'registrada', etc., if used as a standalone adjective).
The Passive Voice
You use 'registrado' with the verb 'ser' (to be) to show that someone or something received the action (the passive voice): 'El evento fue registrado por la cámara' (The event was recorded by the camera).
Confusing Verb Forms
Mistake: “Using the base verb 'registrar' instead of the past participle with 'haber'. Example: *Hemos registrar*”
Correction: Always use 'registrado' after 'haber' to form perfect tenses. Correct: 'Hemos registrado la entrada'.

Agreement is Key
As an adjective, 'certificado' must change its ending to match the noun it describes. Use 'certificada' for feminine nouns (e.g., 'carta certificada') and 'certificados/certificadas' for plural nouns.
Forgetting the Gender Change
Mistake: “Una cuenta certificado (A certified account)”
Correction: Una cuenta certificada. (Since 'cuenta' is feminine, the adjective must end in -a.)
