reliability（n.）
"可靠的状态或品质"，1816年，柯勒律治创造，由 reliable 和 -ity 组成。在统计学中，自1910年起。
[Coleridge] evades the only charge brought against [Southey], by repelling one not brought against him, except by his Antijacobin patrons—and answers for his friend, as if he was playing at cross-purposes. Some people say, that Mr Southey has deserted the cause of liberty : Mr Coleridge tells us, that he has not separated from his wife. They say, that he has changed his opinions : Mr Coleridge says, that he keeps his appointments ; and has even invented a new word, reliability, to express his exemplariness in this particular. [from a review of "Biographia Literaria" in Edinburgh Review, August 1817]
“（柯勒律治）回避了（南锡）唯一的指控，却反驳了一个除了他的反雅各宾赞助人以外没有人提出的指控，并且像在玩猜谜游戏一样为他的朋友辩护。有些人说南锡先生背叛了自由的事业：柯勒律治先生告诉我们，他没有和他的妻子分开。他们说他改变了自己的观点：柯勒律治先生说，他按时赴约； 甚至发明了一个新词 reliability，来表达他在这方面的典范。”（引自1817年8月《爱丁堡评论》对《文学传记》的评论）
