常見錯誤
What are common mistakes with "Breadth"?Which "Breadth" sentences look correct but are wrong?
×The breadth of the river is very long.
✓The breadth of the river is very great / The river is very wide.
"Breadth" 指的是寬度，是一個二維的度量（如寬度、廣度），應搭配形容寬廣的形容詞（如 great, considerable, impressive），而非形容長度的 "long"。描述河流的寬度時，更自然的說法是 "The river is very wide."
×He has a wide breadth of experience.
✓He has a broad breadth of experience. / He has wide experience.
雖然 "wide" 和 "broad" 意思相近，但與名詞 "breadth" 搭配的典型形容詞是 "broad"，構成 "broad breadth" 的搭配。更簡潔且常見的說法是直接使用 "wide experience" 或 "broad experience"。
×We need to consider the problem in its full breadth.
✓We need to consider the problem in its entirety / from all angles.
"In its breadth" 不是一個地道的搭配。雖然 "breadth" 可以抽象地表示「廣度」，但更自然的表達是 "in its entirety"（整體上）或 "from all angles"（從各個角度）。若要強調廣度，可以說 "consider the full breadth of the problem"。
×The breadth and length of the room are equal.
✓The width and length of the room are equal.
在描述具體空間尺寸（如房間）時，"breadth" 是較為正式或文學性的用詞，日常對話中更常使用 "width"。在技術性或日常測量語境中，"width" 是標準用詞。
×There is a breadth of new books in the library.
✓There is a wide range / variety of new books in the library.
"A breadth of" 後面通常接抽象或不可數的概念（如知識、經驗、技能），較少直接用於可數的具體物品集合（如書籍）。表達「各式各樣」的具體物品時，應使用 "a wide range of" 或 "a variety of"。
