What spanish verb will complete this sentence? ______ es professor aqui?

The verb is already there = es = is. So you need a name: El Señor Sánchez OR an interrogative word: ¿Quién (best choice)

Sra

ESTA EL PROFESOR AQUI?

Que ______,Ana?

To complete the sentence "______ es profesor aquí?" in Spanish, you would need to use the verb "ser". The verb "ser" means "to be" and is used to express permanent or long-lasting characteristics or identities.

To determine the appropriate form of the verb "ser" to use in this sentence, we need to consider the subject of the sentence. Since the sentence is asking about a singular person, we need to use the third-person singular form of "ser". In this case, the third-person singular form of "ser" is "es".

So the correct verb to complete the sentence would be "es". The complete sentence would be "¿______ es profesor aquí?" where the blank space can be filled with a person's name or pronoun to ask if that person is a teacher there.
