What is the Purpose of it?

Definition of "Purpose": the reason for which something is done or created or for which something exists.

So this is seasoning. The reason for this product is to season food. What other purposes could this serve? Being plaster? Can use as insect repellant? 

Multi-purpose vehicles are equally puzzling in my view. What is the purpose of a vehicle, any vehicle? To move stuff / people from one point to another. A car that you can use for shopping and to go skiing? Moves stuff / people from one place to another.
