1. An object pronoun generally precedes the conjugated verb, except if is used in an affirmative command, with an infinitive or gerund.  Then it is attached to the verb as one word.  Déme Ud. el libro.  Give me the book.
2. When you have more than one pronoun, the indirect comes before the direct.  If both pronouns begin with the letter l, then the first one is changed to se.
3. When one or two object pronouns follow and are attached to the verb form, an accent mark must be added to retain the original stress of the word.
4. For clearness or emphasis, the prepositional form of a plus an object of a preposition may be used.  Nos envió a Ud.  He sent us to you.
5. When the preposition con (with) precedes me or te, the words change to conmigo (with me) and contigo (with you).
