credible和 believable的区别

credible和 believable的区别

两者都可以翻译成可信的,是近义词,有时可以通用.
在指可信时,两者都可以指事物或人可信.但是有些微的差别,相较来讲,credible更看重事实可信,客观上可信,就是要提供足够的证据和理由,或者根据已知知识能够被推断为有可能性.believable更倾向于主观可信,表面可信,看似可信即可用believable.
此外,credible还有其它含义,比如有效的有力的 credible forces credible deterrent有效的遏制,有力的攻击.再比如指有极大成功可能性的credible candidate有力的候选人（很可能当选的候选人）.
这些意思believable是没有的.
每一个字典的解释都有些微的差别.我这里以美国的韦氏大学词典和麦克米兰词典的翻译为准.
credible在韦氏词典的解释：
1 :offering reasonable grounds for being believed 1：提供合理的理由相信
2 :of sufficient capability to be militarily effective
capable of being believed especially as within the range of known possibility or probability
2：有足够的能力,在军事上有效.
credible在麦克米兰词典的解释：
1 able to be believed or trusted:1：值得相信或信任：
Boone was not a credible witness.Boone不是个可信的证人.
There was no credible evidence against him.并没有不利于他的可信证据.
2 considered as likely to happen or be successful:2：认为很可能发生或很可能成功：
a credible challenger/opponent/candidate一个有力的挑战者、对手、候选人
believable在韦氏词典的解释：
capable of being believed especially as within the range of known possibility or probability
在已知的可能性范围内,值得相信的,可信的.
believable在麦克米兰词典的解释：
1 seeming possible or true:PLAUSIBLE:看似可能或真实,可能的,可信的.
Their story is hardly believable.例如：他们的故事很难让人相信.
2 described in a way that makes you think something or someone could really exist:CONVINCING:
用一种容易让人信任的方式描述,让你相信确有其事,同convincing.
例如：The leading character in the film wasn't very believable.电影主角不那么真实.
