Questions & Answers about A cabine do karaokê está pronta.
Because cabine is a feminine noun in Portuguese, so it takes the feminine article a.
- a cabine = the booth / the cabin
- o carro = the car
- a sala = the room
A useful reminder: noun gender in Portuguese is grammatical, not logical. Also, words ending in -e can be either masculine or feminine, so you often just have to learn them individually. Cabine happens to be feminine.
Because adjectives usually agree in gender and number with the noun they describe.
Here, pronta describes cabine, which is feminine singular, so the adjective must also be feminine singular:
- a cabine está pronta
- o quarto está pronto
- as cabines estão prontas
- os quartos estão prontos
So pronta matches cabine.
