词根词缀背单词系列之：deduce

deduce [dɪˈdjuːs] 词根：duc = to lead 引导 单词：deduce = de + duc + e 解析：de = down from 从……下来 = to lead (a conclusion) down from (what is proceded) 从（前提）引出以下（结论） 释义：演绎，推理 举个例子：I deduce that she was married by the ring on her finger. 例子释义：我通过她手上的戒指推断出她结婚了。 拓展： 通过deduce可以继续引申reduce(re = backforward)缩小，seduce(se = aside)引诱，其中前缀的de,re,se,都是很常见的前缀，这些需要记录并进行总结，其含义在自由词根和黏附词根中并不一样，duc是黏附词根，所以前面的前缀都是原生词缀表达原始含义。
