¡Hola, anyiochoa32! :D
Respuesta:
Pues... según yo, el Pronombre Personal que suele contraerse es I (es i en mayuscula), ya que en Negative no hay otra forma de contraerse en forma corta, ya que es la única que es posible: I'm not
- Ejemplos de Negative (del Verb 'TO BE'):
I am not ─ I'm not
You are not ─ You aren't ─ You're not
He is not ─ He isn't ─ He's not
She is not ─ She isn't ─ She's not
It is not ─ It isn't ─ It's not
We are not ─ We aren't ─ We're not
You are not ─ You aren't ─ You're not
They are not ─ They aren't ─ They're not
Entiendes?
