Blitzkrieg is like "a war being done quick" or "a war which wont last long and to be ended quick".

I think the key is the understanding of "Blitz", which is associated with things like "fast" "hitting hard" "dangerous" "powerfull" "in a short amount of time" "to release a high amount of energy in a short amount of time" (and so on).

All of these words, formed like a tag cloud, are meshed into the the idea "Blitz" added to the german word for war ("Krieg").

If i think about the german language, its all about abstraction (and precision).
