I'm not a native Spanish speaker but I think I can help you out.
"These" is the plural of "this".
"Those" is the plural of "that" In Spanish, "this" is one of 3 words: 1-"esto"-the indefinite pronoun and it always stands on its own, 2-"este"-the masculine form modifies masculine nouns, 3-"esta" -the feminine form modifies feminine nouns.
The plural is "these". And you lose one of the three versions when you make them plural. There are only 2 versions of the Spanish word for "these". 1- "estos" is both the indefinite form and the masculine form. 2- "estas" is the feminine form.
The Spanish words for "those" follow the very same patterns!
You just drop the "T" in each word.
"Those" equals 1-esos--indefinite and masculine form, 2- esas--feminine version.
I hope that helps!
In English there are two words to refer to an object(s): if it is near, you use this (these), if it is not near, you use that (those).
In Spanish there are three words:
- Este refers to smth near = this.
- Aquel refers to smth not near = that
- Ese is something between these two, not particularly close but not too far away. It can also be used to refer to an object(s) or a person(s) that is closer to a listener than to a speaker. Since English doesn't have a word like that, it can be translated both as "this" or "that".
These words, of course, have different forms depending on the gender and form of the object:
este - esta - estos - estas
ese - esa - esos - esas
aquel - aquella - aquellos - aquellas
