Neuter Demonstrative VS Demonstrative

Neuter Demonstrative VS Demonstrative
 

How would you know when to use neuter demonstrative pronouns over demonstrative pronouns? I know that you use a demonstrative pronoun to replace an actual noun, right? But, I don't know how to distinguish them from neuter demonstrative pronouns.

Use the neuter pronouns when you're talking about unknown or unspecified nouns, situations and ideas.
¿Qué es esto? = What is this?
¿Qué es eso? = What is that?
¿Cuáles son aquellos animales? = What are those animals over there?

If you've other questions, ask.

so, neuter demonstrative pronouns usually are in questions? what would be an example of that in a sentence and not a question?

No entiendo eso. = I don't understand that (unspecified idea or situation).
Esto no me agrada nada. = This (unspecified situation) doesn't make me happy at all.

The neuter demonstrative pronouns (also known as indefinite demonstrative pronouns) never have an accent, while the definite demonstrative pronouns do.
¿Cuál prefieres, ésta o éste? = Which one do you prefer, this (feminine item) or this (masculine item)? (Both items are close to the speaker.)
Ésa, no, aquél. = That one (feminine item, not close to the speaker), no, that one over there.
Tengo un gato y un perro. Ése no duerme en la casa. Here, ése means the latter.

Esto no me agrada nada. = This (unspecified situation) doesn't make me happy at all. <--- for this example for instance, as long as there aren't previous sentences referring to what "THIS" is... you would use neuter demonstrative pronouns?

Would you use neuter demonstrative if it was something like:
"This pie tastes good. This is very delicious" VS if it was just "This is very delicious." then you would use neuter demonstrative if I were to translate that into spanish?

Only if 'this' is unknown or unspecified, meaning you don't know what 'this' is or you aren't hinting at what 'this' is to your audience. If you know what 'this' is, you must use the definite demonstrative pronoun.

In my example, the situation was unspecified, or unknown. If you're talking about an unknown, like finding yourself in a dark alley and hearing a creepy sound behind you, you can say "I don't like this one bit. (Esto no me gusta para nada.)" Here, esto could be the unknown situation or the unknown entity.

thank you for the help Rusty

You're welcome!

Your examples are very interesting for me, then could you give me more examples.

Si quieres pedir ejemplos de algo, es necesario que seas más específico. ¿A quien le estás pidiendo ejemplos? y ¿Ejemplos de qué cosa buscas?

Rusty's examples, they are very interesting, and I want to know more above them, because I have not clear even the examples, I try to understand them, but sometimes I need the translate in Spanish, and I know Rusty cans help me with them, could you give more examples above them.

Thank you.

Write specific examples of what you didn't understand, please. I used idiomatic expressions in my sentences. The Spanish translations I gave in these instances were accurate translations of the idiomatic expressions.

Si hay una frase, un ejemplo o una palabra que uno no entiende, lo mejor es empezar un hilo nuevo y hacer una pregunta específica acerca de esa palabra frase o modismo. Así todo queda más organizado y cada hilo se mantiene más útil para otros porque en el futuro es más fácil encontrarlo porque se trata de un solo tema, no varios. :)

Por ejemplo, este hilo, lo debemos mantener como una discusión o debate acerca del demonstrativo y ofrecer información acerca del demonstrativo.

Ok.
