I am reading a book to explain factorial.

n! = n*(n-1)*(n-2)....3*2*1 

Decompose word factorial阶乘, I am enlightened to see its meaning literally.

Since Factor is 乘数, So factorial should 阶乘.

How to describe such a situation?

"顾名思义"? 从字面上理解? 从拼写上理解?

I assume 顾明思议 a bit better but merely not grasp the idea thoroughly.

Are there some better phases?

  • I think this is just a way to construct English words. Curious to know what other people say. – sylvia Oct 27 '19 at 3:00
  • I don't understand the question. :( – dan Oct 27 '19 at 3:29

    I think the question is motivated by how 阶乘 = "step multiplication" defines itself, and we're asking if there's a way to describe this property other than 顾名思义. (Maybe 明 is a typo for 名?) – Becky 李蓓 Oct 27 '19 at 5:17

    I believe you mad a typo: n! = n*(n-1)*(n-2)....3*2*2 -> n! = n*(n-1)*(n-2)....3*2*1 – tsh Nov 1 '19 at 6:34

What I can think of is: 逐字理解 or 按字面意思理解.

  • I got an idea "说文解字', so '拆字解字' might be an option. – Calculus Oct 27 '19 at 6:38
  • @Algebra those are not suitable because 拆字解字 is used to describe the action itself, not a way to understand. – dan Oct 27 '19 at 6:45

阶为逐级,乘为相乘,以阶乘冠factorial,可谓名实相合。

「顾名思义」可以很好描述这种情况。由「阶乘」的名字可以推断其含义。「顾名思义」不等同于「从字面上理解」。「顾名思义」通常意味着这个名字取得好,很简洁,能准确的反应其意义。如果一个名字很长,例如中华人民共和国中央政府,一般不能使用「顾名思义」这个词,但是可以使用「逐字理解」。「顾名思义」通常还要求对名字的理解/推断是正确的,与它类似的一个词「望文生义」也表示从字面推断其含义,但是对应的推断是错误的。

「顾名思义」好像并没有什么特别好的同义词。
