我是線上《牛津詞典》專業版 (Oxford Dictionaries Pro) 的訂戶，最近注意到網站發布了最新一季的新詞。這一季的新詞共有 45 個，我分批介紹，並加註了自己的翻譯和眉批，附上詞典所提供的例句一條和詞源 (若有)，以饗格友。前六批 (之一～之六) 介紹了按字母順序的頭 30 個，這次介紹第七批再次的 5 個。請注意，這裡的《牛津詞典》不是史上最大的《牛津英語詞典》(The Oxford English Dictionary)，而是以《英語牛津詞典》(Oxford Dictionary of English) 為骨幹，兼納《新牛津美國詞典》(New Oxford American Dictionary) 數位化而成。名字過份類似，的確令人混淆。
