Questions & Answers about Завтра я хочу перечитать третий урок.
читать is imperfective, meaning “to read” (focus on the process, not completion).
перечитать is perfective with the prefix пере-, adding the sense of “read again” or “read through completely a second time.” The perfective aspect also signals that you intend to finish the action.
In Russian, хотеть can govern both aspects, but with different nuances:
• With imperfective (e.g. хочу читать) you express desire to engage in an ongoing action (“I want to be reading”).
• With perfective (e.g. хочу перечитать) you express desire to achieve the result (“I want to finish reading again”). Here, the speaker cares about completing the reading of lesson 3.
