"These": This is the most common translation when "estas" refers to plural feminine nouns. For example:
* Estas flores son hermosas. (These flowers are beautiful.)
"You are": When "estas" is used with the verb "ser" (to be) in the second person plural, it translates to "you are." For example:
* Ustedes están bien. (You are well.)
"They are": Similar to the previous example, "estas" can also mean "they are" when referring to plural feminine nouns. For example:
* Las chicas están en la escuela. (The girls are at school.)
"You are (formal)": In some cases, "estas" can also translate to "you are" in the formal second person singular. This is less common but still possible.
"They are (formal)": Similarly, "estas" can mean "they are" in the formal third person plural.
To understand the meaning of "estas" accurately, it's important to consider the surrounding words and the context of the sentence.
