Assuming I live in the north but come from From the south, from another thread I got to know that we can say it’s starting to get hot down home whereas as it’s starting to get hot home is incorrect, even though "home" can be used as an adverb on its own, which leads me to think, should I say "I’m doing the dishes at home" or "I’m doing the dishes home"? My intuition tells me the former sounds better.
Anyway, can anybody tell me how to use "home" vs "at home" vs "down home"? In which case are they used and how would the meaning change if they are used in place of each other?
