“全國(guó)衛(wèi)生系統(tǒng)外語(yǔ)水平考試：形態(tài)學(xué)”相信是準(zhǔn)備全國(guó)衛(wèi)生系統(tǒng)外語(yǔ)水平考試的朋友比較關(guān)注的事情，為此，醫(yī)學(xué)教育網(wǎng)小編整理內(nèi)容如下：

一、形態(tài)學(xué)的定義

二、Word Formation

（1） Derivation

Derivation shows the relation between roots and suffixes. In contrast with inflections， derivations can make the word class of the original word either changed or unchanged.

（2） Compound

Compounds refer to those words that consist of more than one lexical morpheme， or the way to join two separate words to produce a single form， such as ice-cream， sunrise， paper bag， railway， restroom， simple-minded， wedding-ring， etc.

（3） Invention

Since economic activities are the most important and dynamic in human life， many new lexical items come directly from the consumer items， their producers or their brand names.

發(fā)明法： 發(fā)明法又叫造詞， 指直接用某一種商品的生產(chǎn)商或者商標(biāo)的名字作為該類(lèi)產(chǎn)品名稱(chēng)的造詞方法， 例如，Kodak， Coke， nylon， granola 等， 它們都已經(jīng)成為了代表新事物的新創(chuàng)詞語(yǔ)。

（4） Blending

Blending is a relatively complex form of compounding， in which two words are blended by joining the initial part of the first word and the final part of the second word， or by joining the initial parts of the two words.

混成法：混成法是一種相對(duì)復(fù)雜的復(fù)合形式，由兩個(gè)單詞混合而成， 一般把第一個(gè)單詞的開(kāi)頭部分和第二個(gè)單詞的最后部分連接起來(lái)， 或者是把兩個(gè)單詞的開(kāi)頭部分連接起來(lái)

（5） Abbreviation / clipping

A new word is created by cutting the final part， cutting the initial part or cutting both the initial parts of the original words.

（6） Acronym

Acronym is made up from the first letters of the name of an organization， which has a heavily modified headword.

（7） Back-formation

Back-formation refers to an abnormal type of word-formation where a shorter word is derived by deleting an imaged affix from a longer form already in the language.

（6） Analogical creation

The principle of analogical creation can account for the co-existence of two forms， regular and irregular， in the conjugation of some English verbs.

（7） Class shift / Zero-derivation / conversion

By shifting word class one can change the meaning of a word from a concrete entity or notion to process or attribution.

（8） Borrowing

English in its development has managed to widen her vocabulary by borrowing words from other languages. Greek， Latin， French， Spanish， Arabic and other languages have all played an active role in this process.

三、Morpheme

Inflection is the manifestation of grammatical relationships through the addition of inflectional affixes， such as number， person， finiteness， aspect and case， which do not change the grammatical class of the stems to which they are attached.

屈折詞素就是通過(guò)添加詞綴體現(xiàn)語(yǔ)法關(guān)系，比如數(shù)、人稱(chēng)、有定性、體、格，不改變所附加詞語(yǔ)的語(yǔ)法類(lèi)。

派生詞綴是加在詞干上構(gòu)成新詞的詞綴。這種構(gòu)成新詞的方法叫派生法，所構(gòu)成的詞叫派生詞。

派生詞綴又根據(jù)在單詞中的位置分為前綴和后綴兩類(lèi)。前綴出現(xiàn)在單詞的前邊。前綴的主要功能是改變?cè)~干的語(yǔ)義，一般來(lái)說(shuō)前綴不改變?cè)~的詞性，如，當(dāng)我們?cè)趂riendly前邊加上un-時(shí)，它的語(yǔ)義發(fā)生了改變，但是單詞的詞性不變。但是，也有一些例外情況，如：unearth， enlarge， prewar等。后綴加在詞干的后邊。后綴主要改變?cè)~性，也可以改變語(yǔ)義的功能。
