Guten Tag RexV und sfpugh,
Thanks for your questions RexV, and for your answers sfpugh! I just wanted to add a couple of things to sfpugh's responses:
Wird es Heute noch fertig?
As sfpugh's German friend correctly pointed out, noch can be used to add emphasis, and it can often be translated as "still" or "yet" in English. To understand exactly what sort of emphasis words like noch provide in a sentence, it can be helpful to look at a literal translation. Here, this would be: "Will it be finished yet today?" You wouldn't naturally say this in English, but you can see the sort of effect that noch has.
For a concise explanation of the many uses of noch, check out this other forum thread: https://www.rocketlanguages.com/forum/german-grammar/nach-and-noch/.
As sfpugh correctly says, zum comes from combining zu + dem, and dem is the masculine or neuter form of "the" in the dative. Similarly, zur comes from combining zu + der, and der is the feminine form of "the" in the dative.
