Final answer:
Estar is not used to state characteristics about a person, but it is used to state location, mood, and feelings in Spanish.
Step-by-step explanation:
Estar is a verb in Spanish that is used to express temporary states or conditions. It is not used to state characteristics about a person, as that would require the use of the verb ser. For example, to say that someone is tall, you would use ser: "Él es alto."
However, estar is used to state a person's location, mood, and feelings. For example, to say that someone is at the park, you would use estar: "Él está en el parque." To say that someone is sad, you would use estar: "Él está triste." And to say that someone is feeling tired, you would also use estar: "Él está cansado."
