2.10.2前缀hexa-,sex=six(六);sept-=seven(七)【视频】

《高中英语单词思维导图速记宝典》

hexa-=six表示“六”,源于古希腊语,six源于古英语的sex,e异化为i,sex(性别)恰好是分开男女之后才有的概念,本义是“区分,分开”,而six恰好是十二进制的一半,也和“分开”有关。

sept-=seven表示“七”,源自拉丁语,seven源于古英语。September[səp'tembə]n.九月,是怎么回事呢?古罗马皇帝朱里斯·凯撒(Julius Caesar)之前的历法以March(三月) 为第一个月,共十个月,September是第七个月,后来改革历法,加上了一月(January)和二月(February)成了十二个月,但原来的月份名称未变, 依次往后顺延两个月,这样September ,October,November和December分别是旧历法中的七月,八月,九月和十月,现在就成了九月,十月,十一月,十二月。
