While looking for etymology of word Chemistry. I found it's derived from word Kemia or Alchemy which means "Cast together". Now I'm struggling to know its meaning/translation. I've looked in the dictionary but it gives different meanings for word "cast" I don't know which one is correct in this context. Moreover, there is no phrasal verb like this.Yet I am of view that it means "to put things together".
