Use the affirmative imperative form of leer to issue a command instructing someone to read something.  Note that there is no imperative conjugation for the singular first person "yo," or "I" in English, because you cannot issue a command to yourself. Example: "Read the newspaper," Lee el periódico.  tú: lee él/ella/usted: lea nosotros/-as: leamos vosotros/-as: leed ellos/ellas/ustedes: lean When you need to tell or command someone to not read something, you would use the negative imperative, which differs from the affirmative imperative.  Note that there is no imperative conjugation for the singular first person "yo," or "I" in English, because you cannot issue a command to yourself.
