Learn German: Ich esse das Gemüse, obwohl ich schon satt bin. - I am eating the vegetables although I am already full.

The word obwohl (although) is a subordinating conjunction. This means it introduces a dependent clause and forces the conjugated verb (bin) to move to the very end of its clause.

Why do we use satt here instead of voll for "full"?

In German, satt is used specifically to mean you are full from eating. If you used voll, it would sound like you are a physical container that is filled to the brim, or it could be understood as slang for being drunk!

Why is it das Gemüse (singular) when in English we say "the vegetables" (plural)?

In German, Gemüse is usually treated as a collective singular noun (neuter, so it takes das). It refers to vegetables as a general category of food, much like how we say "fruit" in English instead of "fruits".

Is the comma before obwohl mandatory?

Yes! Unlike in English, German grammar requires that subordinate clauses (like the one starting with obwohl) are always separated from the main clause by a comma.
