Write each of the forms of the verb estar in the present tense. Then demonstrate how to use the verb by writing a sentence using

one of the forms.

Yo estoy

Tú estás
Él/Ella/Usted está
Nosotros/Nosotras estamos
Vosotros/Vosotras estáis
Ellos/Ellas/Ustedes están

Sentence: Yo estoy cansado de tanto trabajo. (I am tired of so much work.)

Sure! Here are the forms of the verb "estar" in the present tense in Spanish:

- Yo estoy (I am)
- Tú estás (You are)
- Él/Ella/Usted está (He/She/You(formal) is)
- Nosotros/Nosotras estamos (We are)
- Vosotros/Vosotras estáis (You all are)
- Ellos/Ellas/Ustedes están (They/You all(formal) are)

Now, let's form a sentence using one of the forms.

Example sentence: Yo estoy en casa. (I am at home.)

To write each of the forms of the verb estar in the present tense, we need to conjugate it according to the subject pronouns. The verb "estar" means "to be" in English, and in the present tense, it can be conjugated as follows:

- Yo (I) estoy
- Tú (You, informal) estás
- Él/Ella/Usted (He/She/You, formal) está
- Nosotros/Nosotras (We) estamos
- Vosotros/Vosotras (You all, informal) estáis
- Ellos/Ellas/Ustedes (They/You all, formal) están

To demonstrate the usage of the verb "estar," let's form a sentence:

"Tú estás en la biblioteca." (You are in the library.)

In this sentence, we use the second-person singular form of estar, which is "estás," to indicate that the subject "tú" (you, informal) is in the location mentioned, which is "la biblioteca" (the library).
