Specialty、speciality 和 specialism 之對與錯

• Shell carvings are a specialty of Penghu. (貝殼雕刻是澎湖的特產) (正)
• Shell carvings are a speciality of Penghu. (正)
• Shell carvings are a specialism of Penghu. (誤)

解說：Specialty 意為「特產，名產；專業，專長」，為美式拼法；speciality 也意為「特產，名產；專業，專長」，為英式拼法；specialism 亦是英式拼法，但僅有「專業，專長」的意思。這三個字都是可數名詞。

• His specialty is geoscience. (他的專業是地球科學) (正)
• His speciality is geoscience. (正)
• His specialism is geoscience. (正)
