用法筆記

Frequently used in informal contexts. In formal writing, alternatives such as 'extremely fast' or 'high-speed' are often preferred. The variant spelling 'superfast' (one word) is also common. Avoid intensifying with 'very' since the prefix 'super-' already carries the meaning of 'extremely'.

常見錯誤

❌This computer is very super-fast.
✅This computer is super-fast.
💡'super-' already means 'extremely', so 'very' is redundant.
❌The super-fast train is a high-speed rail system.' (redundant)
✅The super-fast train runs on a dedicated rail system.
💡'super-fast' already expresses high speed; avoid pairing with 'high-speed' in the same clause.
