The indirect object of a sentence usually answers the question ‘to whom?’ or ‘for whom?’: Roberto me da un regalo (‘Roberto gives a present to me’); Yo te compro este libro (‘I'll buy this book for you). To replace the indirect object noun with a pronoun, you must choose the correct form that corresponds to the noun:
 

Sometimes native speakers will use le or les as both the direct and indirect object pronoun when they are referring to a male person. If you are not sure which form to use (le or lo) when talking about a man, you can almost always use le.
