relation与relationship辨析
词缀分为前缀prefix和后缀suffix，后缀往往改变单词的意思和词性。这个－ship，表示的是一种：关系，是那种抽象的关系，内在的关系。
Relation和relationship这两个词指关系时是相同的，尤其用于指事物之间的关系：
Some doctors think there is a relation between smoking and lung cancer.
空手道段位颜色有些医生认为吸烟与肺癌有关连。
Scientists have rearched into the relationship between smoking and lung cancer.
科学家曾研究吸烟与肺癌的关系。
There is no proof of the relation of crime to TV violence.
无证据显示罪案是和电视上的暴力有关的。
I am doubtless about the relationship of diligence to success.
我绝不怀疑勤奋与成功的关系。
“What relation is he to you?”“He is nephew to me./He is my nephew.”
“他和你有何关系？”“他是我的侄儿。”
“What is his rela tionship to/with you?”
“他和你有何关系？”
（注：这句不能说成：“What is his relation to you?”）
在以上情况下，即使有分别，relation侧重形式上的关连，而relationship却侧重密切的交往。例如：
John's relation with Mary is father and daughter.
约翰和玛丽是父母关系。
John's relationship with Mary has improved.
约翰和玛丽的关系已改善了。
Relation和relationship最大分别在于relation用于较广，可带别的涵义，如：
（一）加了s，变成复数的relations指密切交往上的关系而非形式上的关系。例：family relations、business relations、foreign relations、friendly relations（但也可写成friendly relationship、a love－hate relationship）.
（二）解作“亲属”，相等于relative。但一般已多用relat ive代替relation：
My niece is my near relation/relative.
我的侄女是我的近亲。
（三）用在固定词组里，如：in relation to（有concerning的含义）：
He was arrested in relation to the murder ca.
他涉及那桩谋杀案被拘捕。
Questions have been raid in relation to the legality of abortion.
对于堕胎的合法性有人提出质疑。念叨是什么意思

5．比较relation和relationship：
a．relationship的用法最广，包括了relation和relations的许多涵义。relation和relationship 可以用来表示亲属关系。例如：
A relation of mine is coming to stay. 我有个亲戚要来这里暂住。
－What’s your relationship to her? 你和她是什么亲戚？
－She is my cousin. 她是我的表妹。
b．relationship 可以指强烈的感情关系。例如：
Their relationship has lasted many years. 他们的感情已经有很多年了。
c．如果不侧重个人关系或友谊时，可以使用relations或者relationship。例如：

d．relation和relationship可以表示事物之间的相似之处或者一致性。例如：
Some people say that there is no relation / relationship between violence on television and crimes of violence in life. 有人说电视中的暴力镜头和生活中的暴力犯罪并无关系。
RELA TIONS 和RELA TIONSHIP在表示两者（人，国家，ETC）关系这个意思上面，如果没有什么感情的意思是可以混用的。比如中美关系，两者都可以
和FRIEND，FRIENDSHIP；MEMBER，MEMBERSHIP的关系类似，但要复杂一点，主要原因是在
于RELA TION本来就是抽象的东西。FRIENDSHIP可以看成FRIEND之间的一种关系。RELA TIONSHIP也可以看成RELA TION的关系，就是关系的关系。
比如：
THE RELA TIONSHIP BETWEEN ME AND MY FA THER，我和父亲的父子关系上的感情写感动的作文
层面的关系，可以用好或者不好来形容
THE RELA TION BETWEEN ME AND THIS MAN IS SON AND FA THER。表示一种客观存在的联系，就是父子联系。就没有好和不好的概念，因为它是客观存在的关系。
因此，RELA TIONSHIP可以带有感情的意思，比如用来指一段恋情。
