"We know little about him."

Translation: Víme o něm málo.

[Mamke1]

What about "My vime malo o nem."

[VladaFu]

It is possible when you strongly stress O NĚM. We know little ABOUT HIM, not about the other guy.

[Hatch-Slack]

Thank you for your answer.
Would be the English version with stress on "about him" : "About him, we know little."?
Sorry for being so insistent, things started to be clearer now.

[VladaFu]

Perhaps...

But I meant "We know little about HIM." pronounced with a strong emphasis on HIM.

[Hatch-Slack]

Yes, I got that.
I presumed "About him, we know little." as an English neutral form of saying "My víme málo o něm." (excluding the intonation for stress).
It seems that the intonation in Czech is not so crucial, as the construction of the sentence shows the stress by itself.

[nueby]

It is he/him (that) we know little about. or It is about him (that) we know little.

[Hatch-Slack]

For an unknown reason, it does not work this way in Czech.

What is wrong with: Vime malo o něm?

[VladaFu]

That is really strange. If you really want to stress that it is HIM about whom we know little, we would use:

Málo víme o něm.

[BrianSille2]

In English there is a subtle difference between "We know little..." and "We know a little...", The former having a negative connotation and the latter positive. Can they be distinguished in Czech?

[VladaFu]

"a little" is normally translated as "trochu", "něco málo". Not as just "málo".
