QUES: The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth). German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746. Work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron (hot-dip galvanizing) is the major application for zinc. Other applications are in batteries, small non-structural castings, and alloys, such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate (as dietary supplements), zinc chloride (in deodorants), zinc pyrithione (anti-dandruff shampoos), zinc sulfide (in luminescent paints), and zinc methyl or zinc diethyl in the organic laboratory.

QUES: Hokkien dialects are typically written using Chinese characters (, Han-ji). However, the written script was and remains adapted to the literary form, which is based on classical Chinese, not the vernacular and spoken form. Furthermore, the character inventory used for Mandarin (standard written Chinese) does not correspond to Hokkien words, and there are a large number of informal characters (, the-ji or thoe-ji; 'substitute characters') which are unique to Hokkien (as is the case with Cantonese). For instance, about 20 to 25% of Taiwanese morphemes lack an appropriate or standard Chinese character.
