When to use "este" instead of "esto" or "esta"?
I am confused because it seems "este" is neither masculine or feminine so I don't know when I would use it. Thank you for any help!

Question

Answer

"Este" is masculine. Examples:

Este carro. This car
Este trabajo. This job
Este dormitorio. This bedroom
Este trabajador.. This worker

"Esta" is feminine. Examples:

Esta mujer. This woman
Esta doctora. This female doctor.

The word "esto" Using when the sentence  have no gender or is undefined. Examples:

Yo no quiero esto. I don't want this.
Esto es malo. This is bad.
Necesitamos trabajar para esto. We need to work for this.
