superspeedy
Faster than fast
Superspeedy means extremely fast, an emphatic intensification of speedy.
The prefix super- amplifies rather than transforms: The superspeedy delivery arrived within an hour.
The word is informal and often playful, favored in casual speech and children's contexts over more technical alternatives like ultrafast.
