I know when placed after a verb it means "seems like" or "looks like", but what I want to know is what the そう in
そう です か
means. I know そう です か means "Is that so?" but I've seen そう used with other words and I'm not sure what exactly it means. Does it even have a meaning on its own or is its meaning affected by the characters that follow it?
I know this might seem like a translation question but whenever I tried to search for an answer online I was only really able to find answers relating to how to use Sou when attached to verbs.
