n.|big ticket/dearness;高價，昂貴性
"expensiveness"是形容詞"expensive"的名詞形式，指某物價格昂貴或成本高昂的特性。該詞由詞根"expens-"（源自拉丁語"expendere"，意為"稱量、支付"）和名詞後綴"-ness"構成，表示某種狀态或性質。
在語義層面，該詞包含三層核心含義：
在語言學應用中，該詞多用于正式語境，常見于經濟學論文、市場分析報告及産品評測中。其近義詞包括"costliness"和"dearness"，但語義側重有所不同——"costliness"更強調實際成本，而"expensiveness"側重價格感知（《韋氏大學詞典》詞條對比）。
值得注意的特殊用法出現在莎士比亞戲劇《李爾王》中，該詞曾被借喻為"情感代價的沉重性"，這種文學引申在現代文本分析中仍有應用案例（參考劍橋大學出版社《文學術語詞典》）。
