根據一項最新調查顯示，英國人最常拼錯的單字是definitely（肯定地），常被誤拼成definately。容易拼錯的英文單字前三名分別是 definitely，sacrilegious（該受天譴的）和indict（起訴），怎麼拼才對，英國人經常霧煞煞。
此外，mortgage（貸款）拼成morgauge，speech拼成speach也是常見錯誤。
即使名人也會拼錯字，最經典的例子就是美國前副總統奎爾，他和小學生玩拼字糾正對方potato（馬鈴薯）拼錯了，應該是potatoe，結果是他錯了。 另外英國首相布萊爾拼錯了tomorrow為toomorrow達三十年。
下列是在學生英文作文中常見容易拼錯的英文單字，您可以看看你是否也曾犯同樣的錯誤。
