Overview
Objects pronouns (direct, indirect, and reflexive) are placed before the conjugated verbs they are associated with.
Le digo “te tengo que enseñar cómo se usa”, y me dice “pues ya lo probé” y no sabía nada.I tell her “I have to teach you how to use it”, and she says to me “well I already tried it” and she didn’t know anything.
However, with affirmative commands and non-conjugated verbs (e.g. infinitives or gerundives), the pronoun objects are attached to the end of the verb.
Dime qué cómoda te sientes al hablar el inglés.Tell me how comfortable you feel speaking English.
Direct and Indirect Object Pronouns Together
Sometimes there will be both a direct and an indirect object pronoun in the same sentence. The indirect object pronoun always precedes the direct object pronoun. As for their placement in relation to the verb, the general placement rules apply, so both indirect and direct object pronouns precede conjugated verbs (except with the affirmative imperative) or follow non-conjugated verbs, written as only one word in the latter case.
