There is no tense in Spanish that resembles the English present progressive, which expresses actions or situations in progress at the present time that do not continue indefinitely. But there is a verbal periphrase constructed with the present tense of the verb estar (estoy, está, estás, están, estamos), + the gerund of the verb that expresses the action or state that resembles the English present progressive.
