Blitzschnell

Blitzschnell is a German compound adjective meaning extremely fast or lightning-fast. It combines blitz, meaning lightning, with schnell, fast, to emphasize immediate speed or rapid reaction.

The term is used across everyday language, journalism, advertising, and technical writing to describe people, processes, or devices with very short response times. Examples include: "Der Läufer war blitzschnell," "Der Computer bootete blitzschnell," or descriptions of software with "blitzschnelle Ladezeiten." It conveys a vivid sense of speed beyond ordinary quickness.

In grammar, blitzschnell is written as one word and is usually lowercase within running text (blitzschnell). It can be capitalized if used as a brand name or at the beginning of a sentence; as a noun it is uncommon. In formal writing, one might instead use phrases like "extrem schnell" or "äußerst schnelle Reaktionszeiten" to achieve a similar sense.

Notes on usage: Blitzschnell is widely understood in German-speaking regions and is often employed in marketing and media to evoke speed. It is not a fixed technical term with a single canonical definition, and it does not designate a specific entity on its own. When used as a brand or product name, capitalizing or styling it as a proper noun is possible.
