常見錯誤

❌The room was insufficiently big for twenty people.
✅The room was not big enough for twenty people.
💡with simple everyday adjectives, English usually prefers 'not ... enough' to the more formal 'insufficiently'.
❌We had insufficiently chairs for the guests.
✅We had insufficient chairs for the guests.' or ✅ 'We did not have enough chairs for the guests.
💡'insufficiently' is an adverb, so it cannot modify a noun directly.
