用法說明
How is "Buoyant" different from similar structures?What usage mistakes are common with "Buoyant"?
buoyant doing vs buoyant to do
- buoyant doing 通常描述一種持續的、內在的狀態或性質，強調主體本身具有的、能產生浮力的特質或傾向。
- buoyant to do 則較少用於描述人的直接意圖，但可能出現在特定上下文中，表示「（某物）足以使...浮起」或引申為「（情緒、氣氛）令人感到振奮去做...」。
- 在描述物理性質時，buoyant 後通常接名詞（如 a buoyant material）或單獨使用，接動詞結構的情況較為罕見且語意特殊。
- 其用法區別不如 "like doing/like to do" 那樣常見和固定，需根據上下文判斷是描述固有屬性還是產生的效果。 EN: Cork is a buoyant material, perfect for life jackets. 翻譯: 軟木是一種有浮力的材料，非常適合用來做救生衣。
EN:The market sentiment was buoyant enough to encourage new investments.
翻譯:市場情緒足夠樂觀，足以鼓勵新的投資。
總結建議
描述物理浮力或比喻性的樂觀情緒時，通常直接使用 "buoyant" 作形容詞修飾名詞，或使用 "buoyant enough to + V" 來表示「足以讓...浮起或振奮到去做某事」。

常見錯誤
What are common mistakes with "Buoyant"?Which "Buoyant" sentences look correct but are wrong?
×He is very buoyant in the water.
✓He is very buoyant in the water.
This sentence is grammatically correct but often misunderstood. The mistake is in the interpretation: 'buoyant' describes an object's ability to float, not a person's swimming skill or energy level. A person is 'buoyant' if their body floats easily.
×The economy is buoyant because the stock market is going down.
✓The economy is buoyant because the stock market is going up / performing well.
'Buoyant' when describing an economy or market means active, successful, and showing confidence. It is contradictory to use it with negative indicators like 'going down'. Use it with positive trends.
×She has a buoyant personality, always sad and quiet.
✓She has a buoyant personality, always cheerful and optimistic.
'Buoyant' for mood or personality means cheerful and resilient, able to recover quickly from setbacks. It is the opposite of 'sad and quiet'. Common synonyms are 'upbeat', 'cheerful', 'lighthearted'.
×Wood is more buoyant than water.
✓Wood is buoyant in water. / Wood has high buoyancy.
The comparative form 'more buoyant than' is often used incorrectly. Buoyancy is not a simple scale where one material is 'more buoyant' than a liquid. An object is 'buoyant' (able to float) *in* a fluid. For comparison, we say 'more buoyant' when comparing two objects in the same fluid (e.g., 'Cork is more buoyant than pine wood.').
×The buoyant balloon fell quickly to the ground.
✓The balloon, which was no longer buoyant, fell quickly to the ground.
This is a logical contradiction. If something is 'buoyant' (in air), it rises or floats. It cannot be described as 'buoyant' while falling. Use 'buoyant' only for objects that are floating or have the tendency to float.
×I feel buoyant today. (intended meaning: I feel physically light.)
✓I feel light / weightless today.
While 'buoyant' can describe a cheerful mood ('I feel buoyant' = I feel happy/optimistic), it is not used to describe the physical sensation of being light-bodied. Use 'light' or 'weightless' for the physical feeling.
