用法筆記

Uncountable — do not say 'an insomnia'. The condition is typically persistent rather than a single night of poor sleep. Often paired with 'chronic' (長期性的) for long-term cases or 'acute' (急性的) for short-term episodes triggered by stress or illness.

常見錯誤

❌I have an insomnia.
✅I have insomnia.
💡'insomnia' is an uncountable noun and does not take 'a' or 'an'.
❌I couldn't sleep last night, so I have insomnia.
✅I've had trouble sleeping for weeks, so the doctor thinks it might be insomnia.
💡'insomnia' refers to a lasting condition, not a single restless night.
