名词解释

Extension of meaning, also known as generalization, is the name given to the widening of meaning which some words undergo. It is a process by which a word which originally had a specialized meaning has now become generalized.词义的扩大也被称为普遍化，是指词的意义的扩展。这是一个词的词义从表达某一专门的意义转化到表示概括意义的过程。

Narrowing of meaning, also called specialization, is the opposite of widening 16 meaning. It is a process by which a word of wide meaning acquires a narrower or specialized sense. 词义的缩小也称为词义的具体，与词义的扩大相反。这是意义范围较大的词向意义较小的的方向演变的过程

Elevation or amelioration refers to the process by which words rise from humble beginnings to positions of importance.词义的的升格是指原来表示低微意义的词转而成为表示重要意义的词的词义演变过程。

Degradation or pejoration of meaning is the opposite of semantic elevation. It is a process whereby words of good origin fall into ill reputation or non-affective words come to be used in derogatory sense. 词义的降格与语义的升格相反，这是词从表示褒扬或中性的意义向表示贬义的意义的演变的过程

Blending is the formation of new words by combining parts of two words or a word plus a part of another word. Words formed in this way are called blends or pormanteau words. 拼缀法是通过合并两个词的某些部分或一个词与另外一个词的另一部分相加起来构成新词。以此种方式构成的词被称作为拼缀词或拼缀。

Another common way of making a word is to shorten a longer word by cutting a part off the original and using what remains instead. This is called clipping.-另一个常见的构词法时将原词的一部分截去，只用剩下来的一部分构成新词，这种方法叫截短法。

Acronymy is the process of forming new words by joining the initial letters of names of social and political organizations or special noun phrases and technical terms. Words formed in this way are called initialisms or acronyms, depending on the pronunciation of the words.首字母拼音法是将社会组织、特殊的名词词组或技术术语的首字母连起来构成新词的方法。以这种方法构成的词根根据其读音不同又分别叫做首字母缩略词和首字母拼音词。

Back-formation is considered to be the opposite process of suffixation. Words created through back-formation are mostly verbs. 逆生法被认为是后缀法的队里过程。由逆生法生成的词多半是动词。

Morphemes are abstract units, which are realized in speech by discrete units known as morphs. They are actual spoken, minimal carriers of meaning. The morpheme is to the morph what a phoneme is to a phone. -词素（形位）是抽象的单位，是由分立的形素在话语中具体实现的。“形素”是实际说出来的最小的意义携带体形位与形素的关系同音位与因素的关系一样。

Some morphemes, however, are realized by more than one morph according to their position in a word. Such alternative morphs are known as allomorphs.有些词素根据它们在词中的位置不同可有一个以上的不同形素实现，这些不同的形素叫词素变体。

Derivational affixes. As the term indicates, derivational affixes are affixes added to other morphemes to create new words. Derivational affixes can be further divided into prefixes and suffixes. Prefixes come before the ward and the suffixes after the word.派生词缀。是加在其他词
