# decisions
以下内容引用自李平武老师《英语词根与单词的说文解字》:
> 词根: cid, cis[L]= to cut 切
> 常用词decide、decision、concise和precise中有一对同源异形根cid和cis,它们都来自拉丁动词 caedere,意为to cut(切)。cid是现在词干,cis是分词词干。
> decide[de-=away 离;cid=to cut 切;-e→“to cut away 切掉”→“to cut short and bring an end to sth 切断某事使之告结”→]v. settle by giving judgment 裁决;决定/It took months to decide this case. 裁决此案花了数⽉时间。
> decide的派生词:
> ①decidable[decid(e); -able a.]a. 可以决定的;解决得了的
> ②decided[decid(e); -ed a.]a. 决定了的;坚决的
> ③decisive[decide的对应形容词:de-; cis; -ive a.]a. 决定性的
> **decision**[decide 的对应名词:de-=away 离;cis=to cut 切;-ion n.=the act or result 表⾏为结果→]n. the act or result of deciding 决定;决议/The matter is coming to a decision. 事情就要定下来了。
## carefully
以下内容引用自李平武老师《英语词缀与英语派生词》:
>后缀-ful[OE]=Ⅰa. full of~; showing~; having the qualities of~; that can be of~Ⅱ n. as much as a~can fill
>常用词careful与spoonful中含有一个来自英语单词full的派生后缀-ful。它可以加在名词后面构成形容词或名词。1)-ful充当形容词后缀时,读作 / fəl/,它一般加在抽象名词后面,其主要意思为full of〜 (充满…的)。此外,又引申出showing(表现为…的),having the qualities of〜(具有…性质的), having the tendency of〜(易于…的),以及that can be of〜(可…的)。2)充当名词后缀时,-ful读 作/fʊl/,它跟在表示容器、空间的名词之后,意为as much as a〜can hold(一…的容量)。
>**careful**[care n. ⼩⼼,关怀;-ful→]a. ①showing care; done with thought and effort细⼼的;精⼼的;细致的 / Arithmetic requires careful work. 做算术要细⼼运算。②full of care or concern关⼼的,爱护的 / She was careful of the feelings of others. 她很注意体谅别⼈的感情。
