Both direct and indirect object pronouns are the same except for the third person singular and plural forms.
Direct object pronouns:
|cuadro27|| || || |
|lo ||him,it||los ||them|
|la ||her,it||las ||them|
Indirect object pronouns:
|cuadro28|| || || |
|me ||from/to me||nos||us|
|te||from/to you||os||from/to you all|
|le ||from/to him, her, you||les ||from/to them, you|
Direct object pronouns are used in place of nouns that directly receive the action of the verb.
Direct pronouns answer the questions ¿qué? and ¿quién? (what? and who?), while indirect ones answer the question ¿a quién? (for whom? and to whom?).
Indirect object pronouns always refer to people and are used when the action of the verb is directed to or from the person or persons. Since the indirect object pronoun le can refer to him, her, or you, Spanish often clarifies such a sentence by the addition of a + the appropriate prepositional form.
Direct pronoun lo can also refer to actions, situations or ideas in general. In such a case it expresses English it or that.
