Chapter 3 Morphological Structure of English Words We have discussed the historical, cultural and social factors that facilitate (使……容易；推动) the development of the English vocabulary. Borrowing, as we see, has been playing an active role in the expansion of vocabulary. In modern times, however, vocabulary is mainly enlarged on an internal basis. That is, we use word-building material available in English to create new words. But before we discuss the actual ways and means to make new words, we need to have a clear picture of the structure of English words and their components (成分) —word-forming elements. This chapter will discuss morphemes(语素；词素), their classification(分类) and identification(辨别), the relationship between morphemes and word-formation(构词法). 3.1 Morphemes

Traditionally, words are usually treated as the basic and minimal units of a language to make sentences, which are combinations of words according to syntactic rules(句法规则). Structurally, however, a word is not the smallest unit because many words can be separated into even smaller meaningful units. Take decontextualization for example. This is one word, but can be broken down into de-, con-, text, -a/ , -iz(e), -ation ,

each having meaning of its own. These segments (部分) cannot be further divided; otherwise, none of them would make any sense. Though -ation has a number of variants (变体) such as -tion, -sion, -ion, they belong to the same suffix as they have the same meaning and grammatical function and occur owing to (因为；根据) different sound environment. These minimal meaningful units are known as morphemes (morphe is the Greek word for 'form'; -eme as in 'phoneme' (音素) means 'class of' ). In view of word-formation, the morpheme is seen as 'the smallest functioning unit in the composition of words' (Crystal 1985). Syntactically(从句法上看), however, a morpheme is the minimal form of grammatical analysis (语法分析). For instance, each of the word-forms studies, studying, studied, consists of the morpheme study + ; the forms -es in studies, -ing in studying, -ed in studied are morphemes, which express grammatical concepts (语法概念) instead of deriving new words (See Classifying Morphemes).

3.2 Morphs and Allomorphs(词素变体)

Morphemes are abstract units, which are realized in speech by discrete units (具体单位) known as morphs (形素). 'They are actual spoken, minimal carriers of meaning' (Bolinger and Sears 1981:43). In other words the phonetic or orthographic

strings(语音串或拼写字串) or segments (切分成分；节) which realize morphemes are termed 'morphs' (Bauer 1983:15). The morpheme is to the morph what a phoneme (音位) is to a phone (音素). Most morphemes are realized by single morphs like bird, tree, green , sad, want, desire, etc. . These morphemes coincide (巧合) with words as they can stand by themselves and function freely in a sentence. Words of this kind are called mono-morphemic words. Some morphemes, however, are realized by more than one morph according to their position in a word. For instance, the morpheme of plurality {-s} has a set of morphs in different sound context, e. g. in cats /s/, in bags /z/, in matches /iz/. The alternates (作为替换的事物) /s/, /z/ and /iz/ are three different morphs. The same is true of the link verb morpheme {be}. Its past tense is realized by two distinct orthographic forms was , were, each of which happens to be a word-form, realizing {preterit} and {singular}, and {preterit} and {plural} respectively and each has its own phonetic form /woz/ or /w?:/. Therefore, both was, were and their phonetic forms /woz/ and /w?: / are morphs (See discussion in Bauer, p15). An allomorph refers to a member of a set of morphs, which represent one morpheme. Just as we class phones(音素) together as allophones (音位变体) of a single phoneme(音位), so we
