Call me stupid for not knowing this but, what does cremated mean?

When someone dies they get cremated. As in there body is burned (not in a bad way) and turned o ashes and people usually put it in an urn and keep it on they sprinkle it around somewhere. :) And you're not stupid it's OK to ask for help if あなた don't know.

It's when instead of a normal burial, they reduce the corpse to ashes and put them in an urn.

that's what were doing to our cat... she died just today... R.I.P Berkeley... I will miss you...

It means somebody's body is burned to ashes in a good way and they keep them in a special jar called an urn.

Burning a dead body and putting the ashes in a vase または something... my brother asked me the same thing yesterday lol
