My children are arguing loudly and to make them stop I yell:
Enough!
Is that natural? Or should it be:
That's enough!
You say That's enough
to tell someone, especially a child, to stop behaving in a silly, noisy, or unpleasant way.
Whereas,
Enough
gives more angry vibes because it, as we know, means something in an adequate amount. Therefore, saying only a single word (and that also in another reference) Enough is a bit rude.
