Tiengo dudas para usar el Pronombre Lo.

Question

¿Cuando uso el pronombre Lo?

Answer 1

For starters:

http://www.spanishdict.com/topics/show/15

We use pronouns, most often, to refer to a person or object which has already been introduced. It keeps the writing or speaking from sounding repetitive.

Without a pronoun.

Juan is my friend. I know Juan well.

Juan es mi amigo. Conozco a Juan bien.

With a pronoun.

Juan is my friend. I know him well.

Juan es mi amigo. Lo conozco bien.

.

Note that LO can also be a relative pronoun, which is slightly different in indication and function. It's good to know that both of these exist so their different uses don't confuse.

The book that I brought with me. El libro lo que traje conmigo.

.

Note that LO QUE can be gender neutral, and refer to abstract things that don't necessarily have a gender attached.

¡No te olvides de la "a" personal! "Conozco bien a Juan" - pescador1, Dec 3, 2012

There, fixed, thanks. There is a good example of an advantage to using the pronoun - it can cover up not remembering to use the personal 'a' :) - rogspax, Dec 3, 2012

DARN! You are correct, and I make that mistake TOO often. I hope I get that right one day. In the meantime, thanks for keeping me honest. - rogspax, Dec 3, 2012

Answer 2

Or with objects.

I have too many books. I don't want to bring the books.

Tengo demasiado libros. No quiero traer los libros.

I don't want to bring them No quiero traer los.

Note that the pronoun has to agree in quantity and gender.

Thus EL libro becomes LOS libroS.

Thanks Rogspax, I have studied this subject but I forgot. - Carlosserra, Dec 3, 2012
