Direct object pronouns in Spanish include me, te, lo, la, los, las. The direct object receives the action of the verb and can be represented by either a noun or a pronoun, but not both in the same sentence. If the direct object pronoun is the object of a conjugated verb, it is placed before the verb. If it is the object of an infinitive verb, it can be placed before the conjugated verb or attached to the end of the infinitive.
