Here's a breakdown of the phrase:
* Esta: This (feminine singular)
* también: also, too
The phrase is used to indicate that something is included or applies in addition to something else that has already been mentioned.
Examples:
* "Quiero un café y un té. Esta también." (I want a coffee and a tea. This one too.) - This means the speaker also wants another drink, such as a juice.
* "Me gusta la pizza y esta también." (I like the pizza and this one too.) - This means the speaker also likes another food item, such as pasta.
It's important to note:
* The gender of the noun being referred to will affect the form of "esta." For example, if the noun is masculine, you would use "este" instead.
* "Esta también" can be used in both formal and informal contexts.
