whichever and whatever
whichever/whatever flavor of popsicle you have.

I know that whatever is more general and whichever is more specific. but when is something general or specific? is it when i know the type of popsicle the vendor has, then I have to use "whichever" but if I just know the vendor has popsicle but I don't know what kind of it he has, then I have to use "whatever"? correct me if I'm wrong.

Answer

You are mostly correct...
But in your example you are telling the vendor to chose the flavor for you.
"Can I have a popsicle please?
"What flavor?"
"Whichever flavor you have."

You are assuming he only has one flavor.
If you want to know your option of flavors you would ask, 
"What flavors do you have?" or "Which flavors do you have?"

Hi Alexis

"Whichever" is generally to be preferred when choosing from among a restricted set of options (such as a list of flavors or days of the week)
"Whatever" is more general as you said.

For the vendor, you don't know at first what flavor you want so you ask for 'whatever' flavor he has.
The vendor then lists the limited options and tells you to pick 'whichever' you would like.

Answer

"I would like whatever flavor of popsicle you have, sir."  "We have grape, cherry, and lime and you may have whichever one you prefer, ma'am."
