常見錯誤
What are common mistakes with "Brash"?Which "Brash" sentences look correct but are wrong?
×He is a brash person, so he is very shy.
✓He is a brash person, so he is very bold and outspoken.
「brash」意指魯莽、自以為是或唐突，與害羞（shy）的意思完全相反。使用時應注意其含義是過於自信或粗魯，而非缺乏自信。
×The brash decision was made after careful consideration.
✓The brash decision was made impulsively, without careful consideration.
「brash」形容的決定或行為通常是輕率、衝動且未經深思熟慮的。若經過仔細考慮（careful consideration），則不適合用「brash」來描述。
×I like his brash style of painting; it's very subtle and delicate.
✓I like his brash style of painting; it's very bold and eye-catching.
「brash」用於風格時，常指大膽、醒目、甚至有些刺眼或俗豔，與細緻（delicate）、微妙（subtle）的風格形成對比。使用時需注意語義搭配。
×The new employee was brash enough to admit his mistake.
✓The new employee was humble enough to admit his mistake.
「brash」帶有負面含義，形容人魯莽、自以為是。承認錯誤通常被視為謙遜（humble）的表現，與「brash」的特質不符。此為語義誤用。
×This metal has a brash surface.
✓This metal has a brassy surface. / This metal looks cheap and brash.
「brash」主要用於形容人或其行為、風格，不用於直接描述物體的物理表面。若要描述金屬像黃銅，應用「brassy」。若想表達物體看起來俗豔、廉價，可說「looks brash」。
