On “zu” and “um zu”

Hi there,

 

I’ve learnt about sentences with ‘dass’ and ‘zu + infinitive’, but I still don’t feel so confident writing arbitrary sentences that I make up myself. I’ve read the stuff on your site too and this helps loads (much more than many of the boring grammar books); but am still having trouble.

As I understand, it’s okay to write things like, “I know I eat many apples”, in two different ways:

Ich weiss, dass ich viele Äpfel esse.
or
Ich weiss, viele Äpfel zu essen.

But are they really the same? The literal English translation is slightly different:
I know that I eat many apples
vs
I know to eat many apples

Also, I was wondering what is possible to make up the main bit of the sentence (“ich weiss”), not the dependent part. Can it just be anything that can be / needs completing? E.g.,

The sausages, …
On Tuesdays, …
I hope, …

For “I must have forgotten it”, would that be:
ich muß es zu vergessen haben.
ich muß haben, es zu vergessen.

zum + verb

Hello

so today I learned something cool about German

– “das ist zum Haare Reufen = that makes me want to rip my hair out

How versatile is this construction?
Can I also say: “Das ist zum Trinken” or “Diese Musik ist zum das Feiern Lassen.” (this music makes me want to leave the party). Also, how would I say “you make me want to…”? google was no help (as usual) it said “du machst mich wollen etw. zu tun.
would “Du bringst mich zu…” be better. z.B. “du bringst mich zum Lachen (you make me (want to) laugh.)”
I’m sure I’v seen it before, I’m just not totally sure how its said

Vielen Dank im Voraus!

zu – um zu … verbs with zu as a prefix

Hi, Emmanuel

When one uses a zu-infinitive with a verb that has a separable prefix, the zu is inserted between the prefix and the verb. But what if the prefix is “zu” (or “hinzu”)? For instance, if you wanted to say “It is easy to add it to the list”, would you say

“Es ist leicht, das zu die Liste hinzuzufügen”?
