The document discusses the imperfect progressive tense in Spanish. The imperfect progressive, formed with the imperfect tense of estar + the present participle, is used to describe an action that was ongoing or taking place over a period of time in the past. Some examples of how to form the present participle of stem-changing and irregular verbs are provided. The imperfect progressive can be used to describe background actions, while the preterite tense indicates a specific occurrence or interruption in the past.
