How Do I Categorize "Terms" In Module Scripts?

I'm trying to make a Module Script called "Settings", and I want to categorize each "term". Here's what I mean:

local module = {
	Sounds = {
		Touch = 72948375; -- SoundId Example
		TouchError = 75638573; -- SoundId Example
	}
	BrickColors = {
		Orange = BrickColor.new("CGA brown");
		Blue = BrickColor.new("Bright blue");
	}
}

return module
