Personal pronouns of object make reference to people or objects which receive an action and take part into it as well.
|Mi, me, conmigo||Nos|
|Ti, te, contigo||Os|
|Si, se, consigo, lo/la, le||Si, se, los/las, les|
The pronoun of direct and indirect object:
|Indirect object||Direct object|
|Le (se)||Lo/la (se)|
|Les (se)||Los/las (se)|
These personal pronouns have different functions in the sentence, because the transitive verb needs a direct object in order to complete its meaning.
|Direct object pronoun||Indirect object pronoun||Position|
|The 3rd person direct object personal pronouns have some gender and number changes; the indirect object pronouns only change their number. The rest of grammatical persons present the same form in masculine and feminine.
When the direct object makes reference to a singular masculine person, the corresponding pronoun is lo:
|The verbs such as gustar and encantar have to be accompanied by an indirect object. The indirect object can appear two times in the sentence:
||If there is a direct object and an indirect one in the same sentence, the IO (le, les) has to be placed before the DO and it becomes SE
The pronouns are placed before the verb, except with the affirmative imperative, the gerund and the infinitive (in these cases they are placed after the verb and attached to it)
If there is a conjugated verb + gerund/infinitive, the personal pronouns can be placed before or after (if they are before, they have to be written separately and if they are after it, joined).
