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.

词根词缀：-ess

【来源及含义】Greek -issa > Late Latin -issa > Old French -esse > Middle English -esse: a suffix that forms nouns meaning a female +++, as in lioness, tigress, heiress, hostess, and sculptress

【相关描述】When -ess is added to a noun ending in -tor, -ter, the vowel before r is generally elided (eliminated or left out), as in actress (actor + -ess); and such a derivative with the ending -tress (often equivalent to French ) is usually considered a reduced form of Latin -trix, -tricem and popularly regarded as the equivalent of -tor + -ess.

In Middle English many words in -esse were adopted from French; such as, countess, duchess, mistress, and princess, or formed on nouns in -er; such as, enchantress and sorceress.

The suffix -ess is diminishing from English usage, with trends or tendencies toward avoiding any unnecessary references to gender or sexual categorizing (feminine or masculine.

The suffixes -er and -or are no longer gender-specific in modern English: an author or manager, like a doctor or writer, may be male or female, so the words authoress and manageress are considered redundant.

Some -ess words remain in use; for example, heiress and actress, although actor is being used more often now for both men and women.
