"The doctor sees the heart from inside."

Translation: Der Arzt sieht das Herz von innen.

[Amartya1511]

When to use "sieht...aus" combination? I think when the subject is not specified? Is that so??

[gErald18]

Sieht...aus (aussehen) means "to seem", so it doesn't make sense here ;)

[rtackaert]

But why did we use it for the watch example: "wie sieht die Uhr von innen aus?"

[LingPenguin]

Perhaps a better translation for aussehen would be "to look like", which would make the clock example "what does the clock look like from inside?".

[AdrianJosh]

basically, like the mechanical parts..?

[alexfradera]

I'm wondering the same thing.

[sduckwor]

What on earth does this mean ?

[Duckwing63]

From one DUCK to another... It probably means that the doctor (quack! Pun intended) is using a medical instrument and is able to see someone's heart inside their body.

Is "Der Arzt von innen das Herz sieht" incorrect syntax?

[philster043]

Spot's sentence doesn't work because there has to be a verb as the second element of the sentence. Notice both of Christian's sentences have the verb 2nd as well.

[christian]

Yes.

[SpotXSpot]

Could "von innen" be moved at all and still be correct?

[christian]

Der Arzt sieht von innen das Herz.

or

Von innen sieht der Arzt das Herz. (very unusual)

[wataya]

Note that all these variants have slightly different meaning/emphasis. IMHO duo's version is best in conveying the intended meaning.

[gazzamann]

I gave the first one and it was marked incorrect
