词根：ferr(o) = iron 铁

  这个词根派生出来的单词，都是科技词汇，而且多为名词。词根ferr 来源于拉丁语 ferrum 意思是“铁”，这个词根与词根terr 只有一个字母的差别，但是来源和意思完全不同，注意区别。词根ferr 相应的希腊语词根为：-sidero- 铁，如：siderite 菱铁矿、siderolite 铁陨石；③有同类词根（铁属于金属）：-metal-， -metallo- 金属，分别来源于拉丁语 metallum 和希腊语，如：metallurgy 冶金、metallography 金相学、metalloid 类金属。

词根词缀：alumino-, alumin-

【来源及含义】Latin: aluminum [U.S.] and aluminium, [British]

【相关描述】This term was coined in 1812 by its discoverer, the British chemist Sir Humphry Davy, as an alteration of the earlier [1808] New Latin alumium, that was also coined by Sir Davy from alumina, a mineral occurring in nature as corundum plus -ium, a suffix meaning, in this case, "metal").

The variant form aluminium, which is preferred in British usage, also appeared in 1812 as a deliberate alteration of aluminum in order to eliminate confusion because of the partial resemblance to other names of certain elements, such as sodium, potassium, and magnesium, all of which were coined earlier by Sir Davy.
