Sementara itu, passive voice atau kalimat pasif adalah sebuah kalimat di mana subjek dari kalimat tersebut dikenai pekerjaan tertentu. Dengan demikian, subjek tersebut bertindak sebagai penerima sebuah aksi atau receiver of action.
Jika dalam active voice terdapat transitive dan intransitive sentence, maka hanya transitive sentence yang bisa diubah menjadi passive voice. Hal ini lantaran intransitive sentence tidak memiliki objek.
