分析词义"Unknown",这个单词很常见,用来形容一些未知的、不被了解或者不清楚的事物或者人。
列举例句
词根分析"Unknown" 是在词根"know"的基础上加了前缀"un-"和后缀"-n"构成的。“un-”表示否定,“know”表示知道,"-n"是形成形容词的后缀。
词缀分析"Un-"是一个常见的前缀,表示否定。像"unhappy", "unclear", "unwilling",这些单词中的"un-"就表示“不、非”。 "-n"是一个常用于将动词变为形容词的后缀,如known, flown, thrown等。
发展历史和文化背景"Unknown"的词源来自于老英语的"unknowen",最初的意思与现在的意思接近,指的是未知的、不了解的。
单词变形Unknown作为形容词,没有单复数形式。其对应的名词形式是"unknownness",表示未知的状态或品质。动词形式通常用"unknownize",表示使某物变得未知。
记忆辅助你可以把 "unknown" 拆分成两部分:"un-" 和 "known",记住 "un-" 是表示否定的前缀,也就是“不”的意思,"known" 是 "know" 的过去分词,表示“知道”。那么 "unknown" 就是“不知道”的意思。
小故事There was an unknown island, where lived unknown animals. No one knew what it looked like.存在有一个未知的岛屿,居住着未知的动物。没有人知道它是什么样子。
