Morphemes,词素/语素,Word,a fundamental unit of speech and a minimum free form; with a unity of sound and meaning (both lexical and grammatical meaning) capable of performing a given syntactic function,A.

37、 Different from a phoneme: 音素-k /k/,u/ju:/ a/ei, i/ai/A book, I love him.,A morpheme is not identical (同一的) with a syllable (音节), either, since the latter has nothing to do with meaning.

41、eive; s-dogs; exboxes; ed-worked.,B. Roots and Affixes,morphemes may be divided into roots词根 (or root morphemes根词素) and affixes词缀 (or affixational morphemes 词缀语素）,Roots词根,A root is the basic unchangeable part of a word, and it conveys the main lexical meaning of the word.

P.25,Inflectional Affixes曲折变化词缀,An inflectional affix serves to express such meaning as plurality复数, tense时态, and the comparative比较 or superlative degree最高级.,Inflectional affix does not form a new word with new lexical meaning when it is added to another word

46、. Nor does it change the word-class of the word to which it is affixed. The number of inflectional affixes is small and fixed; They have only their particular grammatical meaning.,Plural 复数: -s- es- Genitive case属格： TomsThird person singular present tense第三人称单数: worksPresent participle现在分词: -ingPast

47、 tense and past participle: -ed dComparative: slowerSuperlative: fastest,Derivational affixes派生词缀,When they are added to another morpheme, they derived a new word.

48、ndependent lexical meaning but also affective meaning情感色彩. mis-/ mal-/There are also derivational affixes which can be attached to words of different word-classes. v./ n. +able washable/ marriageable,The number of derivational affixes, although limited, is much larger than that of inflectional affix

49、es. commonly subdivided into prefixes前缀 and suffixes后缀:Prefixes: affixes before the word are called prefixes. Suffixes: affixes after the word are called suffixes.,Both prefixes and suffixes may be grouped according to: Their linguistic origin: Native affixes (are those that existed in English in th

50、e OE period or were formed form OE words.) and Foreign affixes (came as a part of loan words from foreign languages.),Hybrid混合词,: Most foreign prefixes and suffixes have long since become naturalized in English, and many words have been formed form elements of mixed origins. Examples： p.27,Their pro
