Great question!
In Spanish, when you say something like:
Llevo ganados nueve premios.
(I have won nine awards so far.)
The word ganados is a past participle used like an adjective — not part of a compound tense like He ganado
Since it's acting like an adjective, it must agree with the noun (the object) it's describing:
nueve premios = plural, masculine
nine prizes = plural, masculine
So you must say: ganados
"Llevo juzgados 13 homicidios"
= I carry judged 13 homicides
→ Juzgados is describing the homicides (like an adjective: "judged homicides").
The past participles ganados and juzgados are acting like adjectives, not like part of a compound tense (such as he ganado).
That’s why they must agree in gender and number with the direct object (premios, homicidios).
That's why you say:
- Llevo ganados nueve premios ✅
- and not:
- ❌ Llevo ganado nueve premios
