英語單詞的結構

1、英語單詞的結構什么是詞？詞是能獨立運用的、最小的、有語義的語言單位。就其句法功能來說，詞可以分為功能詞(functionword)和實義詞(contentword)兩類。功能詞指的是沒有完整詞匯意義但有語法意義或語法功能的詞，包括、等。實義詞指的是本身有完整詞匯意義的詞，包括英語單詞是由字母拼寫而成的，可以由一個字母組成一個單詞，如，也可以由45個字母組成一個單詞，如：(n.肺塵病)。英語單詞的內(nèi)部結構也不盡相同，讓我們來分析以下三組詞：1. book,books,bookish,bookcase2. tolerate,toleranee,tolerant,toleration,tolerab

2、le,intolerable3. telephone,telegram,telescope,telecommunication在第一組詞里，book可以再分嗎？在第二組詞中，tolerateanceationablein第三組例詞中都有一個共同成分,意思是，-phone有聲音的意思，如microphone;-gram往往表示書寫或描繪出來的東西，如telegram;-scope表示"觀察的儀器，鏡”，女口microscope.從上面的分析可以看出，如果撇出能不能獨立運用這一點，詞就不是最小的有語義的單位，語言中最小的“語音和語義的結合體”稱為"詞素”(morpheme)。上

3、述三組詞中，除了book外，都是由兩個或兩個以上的詞素組成的。什么是詞素？二、派生Derivation前綴前綴含義例詞a-處在arise,aside,aloneen-使可能enrich,enable,enslavedis-dissatisfy,dishonest,disappear,disorder,disagreeun-unable,unknown,uncommon,uncomfortable,unfair,unclose,undress,uncover,untieinim-ir-il-不，非inactive,incapable,inpatient,incorrectimpossible,i
