Originally a Sino-Japanese prefix in formal compounds (超音速 'supersonic', 超大国 'superpower'). Since the 1980s also widely used as a casual intensifier attached freely to adjectives and even verbs (超かわいい, 超忙しい).

- 超大国: superpower
- 超高層: super high-rise
- 超特急: super-express

In casual speech, 超 feels more youthful than すごく or とても and is common among younger speakers.
