Spanish Direct-Object Pronouns

Front 1

Quick reminder: what are the parts to the following sentence:

Compré los libros anoche.
-->I brought the books last night.

Back 1

Subject: Yo (implied)
Conjugated Verb: compré
Direct-object: los libros

*subject + verb + what? or who? = direct object
subject did something to what/who --> the answer = direct-object

Front 2

In order to avoiding repeating the direct-object, use the following d-o pronouns:

me, te, lo/la, nos, los/las

Back 2

Use the correct one based what you want to substitute for:
me = me
te = you
lo = you (formal), him, it (masculine)
la = you (formal), her, it (feminine)
nos = us
los = them (people, things), you all
las = them (people, things), you all, when all are feminine.

Front 3

In a sentence with one verb, the D.O.P. goes before the verb.

Therefore using the earlier sentence:
Compré los libros anoche.

Back 3

(Yo) los compré anoche.
--> I brought them last night.

Front 4

Negative sentence:

the "no" goes before the D.O.P.

Back 4

(Yo) no los compré anoche.
--> I did not buy them last night.

Front 5

If a sentence has more than one verb you have a choice.

Such as in:
Tú quieres lavar las ropas nuevas.

Back 5

1) Tú las quieres lavar.
--> before the first verb
2) Tú quieres lavarlas.
-->attach to the infinite verb
Both mean the same thing:
"You want to wash them."

Front 6

Quick review: gerunds.

Back 6

Verbs that end in:
-ando
-iendo
-yendo

Causes verb to have "-ing" ending

-yendo
-->yéndo-

Front 8
