本研究意圖透過實際例證，來說明「詞彙」的豐富與多變。並透過它和「語音」、「語法」及「語義」間的結合關係來闡明「詞彙學」的重要性。使用的研究場域（field）以近年來報紙所用的標題，做為比較分析的例證。 首章談論定義、研究範圍與方法。第二章則分論：語言中語彙和語音、語法、語義等層次的緊密互動；並藉由台灣的雙語接觸現象，說明對詞彙的影響。第三章則論及「語彙學」此學科和其他相關學科的關聯。如：方言學或語言調查、語用學、應用語言學、心理語言學、計算機語言學或社會語言學等。 第四章談及語彙學和文學的結合所可能發生的連接層面。較具體的是修辭學裏一些辭格的運用，如：譬喻、排比、類字與雙關等，語體風格的關係也會是一個重點。而結論則談論如何追求詞彙的正確運用，是最理想的目標。
