correct: usually implies freedom from fault or error: socially ~ dress.         (fault缺点不足implies a failure, not necessarily culpable, to reach some standard of perfection没有达到完美标准，不一定是过错，如a woman of many virtues and few faults有许多美德少许缺点，如my worst fault is impatience我最大的缺点是没有耐心，he was generous to a fault他慷慨过头了）   error表示严重错误


accurate: implies fidelity to fact or truth attained by exercising care: an ~ description of the whole situation.    （词根CUR表示care细心照料关心，本词accurate准确的字面意思是"去细心照料", 同根词有curator博物馆动物园管理员，cure治疗，sinecure闲职，拉丁中sine表示without，sinecure字面意思是without care）  (fidelity表示faithfulness可信忠诚, Hi-Fi是high-fidelity高保真的缩写，表示重放声音图像与原来的声音图像高度相似。来自词根FID信心信任=faith, trust，如semper fidelis是美国海军陆战队marine corps座右铭，意思是always faithful永远忠诚，如affidavit证词宣誓书)    


exact: stresses a very strict agreement with fact, standard, or truth: a suit tailored to ~ measurements.     强调完全符合一致，又如an exact copy一模一样的副本，an exact account准确详实的说明，to be exact准确来说，an exact science严谨的科学，an exact manager一丝不苟的经理，the exact cause of the fire is unknown火灾具体原因还不知道，he is the exact opposite of his father他和父亲恰恰相反  


precise: adds to exact an emphasis on sharpness of definition or delimitation: the ~ terms of the contract.     （precise和accurate的最大区别是，accurate描述"一次测量a measurement"，如an accurate result准确结果，如an accurate description准确描述；而precise描述"测量系统a measurement system"，如a precision instrument精密仪器，精准扶贫/精准施策/精确的语言/精确的定义等都应该用precision）


nice: stresses great, sometimes excessive, precision and delicacy of action, adjustment, or discrimination: makes ~ distinctions between freedom and licence.  delicate精致微妙灵巧脆弱implies exquisiteness, subtlety or frailty，如the play's delicate charm was lost on screen荧幕上体现不出剧本的精致美妙魅力，如精致微妙的微笑味道语言等

right: is close to correct but has a stronger positive emphasis on conformity to fact or truth rather than mere absence of error or fault: the ~ thing to do.


correct正确: 表示没有过错缺点，accurate准确: 指符合事实真相，需要细心，exact准确: 强调完全符合事实标准真相(very strict agreement)，precise精确:  强调定义定界清晰锐利，nice精细: 表示细致细微，right正确: 和correct相同，但正面强调符合事实真理，而非仅仅无缺点过错
