when to use "esta" estar, este, es

Question

My girlfriend, who is Spanish speaks sentences that frequently involve esta, este es or anything starting with that..and sometimes put the esta and es in the same sentence. How do I know which form of these to use, and when its appropriate to use them

Answer 1

There is no simple answer to that question. If you have a specific example you need help with, post it. If not, you need to look at some lessons.

Take a look at this page

Scroll down to the section that says verbs and take a look at the lessons for ser and estar.

Answer 2

Este, esta and their plural forms are demonstrative adjectives ("this"). Está, estás, etc are from the verb estar, es, eres, etc. are from the verb ser ("to be"). Completely different things.
