OOPS! I found a flaw on... 凸鎚英文

[Wayne]

Native speakers do make mistakes in their speech or writing. Sometimes, the mistake is a tongue slip or a lapse, and other times a blooper or a glitch. Don't be afraid make mistakes when you use English, as native English speakers will do the same.

I read reports on NBA games often on ESPN's NBA websit. Once in a while, I find some mistakes, like this one.

"As Pierce jogged onto the court with a black elastic wrap on his knee, Garnett clinched a fist and screamed, "Yes!"

The word "clinched" actually should be "clenched".

{MACMILLAN English-Chinese Dictionary}
clench: if you clench a part of your body such as your hand or your mouth, or if it clenches, you close it tightly, specially because you are angry or upset. (尤指因生氣或不安)握緊，繃緊，咬緊： He clenched his fists in frustration. 他氣惱得握緊拳頭　I could see the muscles in his jaw clench. 我看得出來他下巴的肌肉繃緊了
延伸學習：字詞搭配
clenched teeth/fists咬牙切齒/緊握雙拳

clinch這個字也值得學習
clinch: to manage to win or achieve something by doing one final thing that makes it certain.最終贏得；最終達成；敲定
clinch a victory/game/deal
Tim Johnson scored the goals that clinched the victory. 提姆．強生踢進勝負關鍵的幾個球
clinch it (for somebody)(使某人)下定決心 {要用"事"做clinch的主詞喔}
