The two values returned by the iterator are the item’s key in the dictionary and the item itself.

local someDictionary = {
	["index 1"] = 5,
	["index 2"] = "hello",
	[game.Workspace.Part] = true
}

for index, value in pairs(someDictionary) do
	print(tostring(index)..": "..tostring(value))
end

would print:

index 1: 5
index 2: hello
Part: true

Although unless you are using integers as your indices and iterating with ipairs, the order in which key/value pairs are iterated may not be guaranteed to be the same as how it is defined in the script.
