单词 discretion 由词根 cret 扩展而来,这个词根的变形也比较多,大家可以根据重点的单词,引申记忆 ~
discretion [dɪ'skreʃ(ə)n]
CET6/SAT/GRE/IELTS
n.慎重;考虑周到;自行决定的自由
discretion 的基本意思是“谨慎,慎重”,由形容词 discrete(adj.分开的,分离的)加上名词后缀变化而来,代表分开来观察思考、决定的状态,还引申出了“自行决定,按某人的意思”的含义,常用于固定短语中。
1)前缀 dis,表示“分开,分离”,例如:
dispense vt.分配,分发
dissect vt.解剖,剖析
disseminate v.宣传,传播
2)词根 cret/cern,表示“观察,筛选”的意思,例如:
discern v.识别,领悟
concern v.涉及,关系到
excreta n.排泄物,分泌物
secretary n.秘书
3)后缀 ion,典型的名词后缀,例如:
expansion vt.扩展,伸展
carnation n.康乃馨
obsession n.痴迷,困扰
★ 变形时刻:discretion = dis(分开)+ cret(观察,筛选)+ ion(表名词)= 分开来观察,仔细筛选 → 表示谨慎,慎重,考虑周到。

carefulness n.仔细;慎重
prudence n.审慎
