| 释义 | 〔diatribe〕Latin diatriba [learned discourse] 拉丁语 diatriba [学术演讲] 〔diatribe〕Listening to a lengthy diatribe may seem like a waste of time,an attitude for which there is some etymological justification.The Greek worddiatribē, the ultimate source of our word, is derived from the verb diatribein, made up of the prefixdia-, "completely,” and tribein, "to rub,” "to wear away, spend, or waste time,” "to be busy.” The verbdiatribein meant "to rub hard,” "to spend or waste time,” and the noundiatribē meant "wearing away of time, amusement, serious occupation, study,” as well as "discourse, short ethical treatise or lecture, debate, argument.”It is the serious occupation of time in discourse, lecture, and debate that gave us the first use ofdiatribe recorded in English (1581), in the now archaic sense "discourse, critical dissertation.”The critical element of this kind of diatribe must often have been uppermost,explaining the origin of the current sense ofdiatribe, "a bitter criticism.” 听唠唠叨叨的絮语也许好象是浪费时间，这是一种态度，一些词源对此有所表明。该词的终源希腊单词diatribe 起源于由动词 diatribein ； 而后者是由前缀dia- “完全地”和 tribein （“消磨、消逝、花费或浪费时间”，“忙于”）所构成的。 动词diartibein 意思是“难熬”、“花费或浪费时间”， 而名词diatribe 意思是“时间消逝、消遣、热衷消遣，研究”， 还有“论文、伦理学论文，伦理学论文或讲演，争辩，论据”。在（1581年）英语中记载的第一次使用diatribe 是热衷于把时间消磨在论文、讲演和争辩中， 现在古体文含义是“论文，批评式的学术演讲”。这种论文所含批评因素必须常常占最主要的，它解释了diatribe 现代含义“尖刻批评”的词源 〔dissertation〕A lengthy, formal treatise, especially one written by a candidate for the doctoral degree at a university; a thesis.（博士学位）论文，（专题）论文，学术演讲：长而正式的论文，尤指大学里由博士学位攻读者所写的论文；学位论文 |
