Questions & Answers about Hoy quiero llevar una trenza antes de salir.
Because querer is a conjugated verb of desire, and the next verb stays in the infinitive.
So the pattern is:
- quiero + infinitive
- quieres + infinitive
- queremos + infinitive
Examples:
- Quiero salir = I want to go out
- Quiero comer = I want to eat
- Quiero llevar una trenza = I want to wear a braid
In this sentence, quiero is the only conjugated verb in the main clause, and llevar depends on it.
Spanish often leaves out subject pronouns when they are clear from the verb ending.
- quiero already means I want
- so yo quiero is usually unnecessary
Both are possible:
- Quiero llevar una trenza
- Yo quiero llevar una trenza
Adding yo can give extra emphasis, contrast, or clarity, but in a normal sentence it is often omitted.
