The document discusses the present progressive tense in Spanish. It explains that the present progressive is used to talk about actions that are happening now or often occur. It provides examples of using the present progressive with common verbs like "comer" (to eat), "bailar" (to dance), and "escribir" (to write). The present progressive is formed by combining the present tense of "estar" with the present participle of the main verb, which is created by adding "-ando", "-iendo", or "-iendo" depending on the verb type.
