盘点那些加了否定前缀之后意思不变的词

sigtemUID: 2169461

大多数词语加了表示否定的前缀之后，如in-，im-，un-，dis-等等，都会变成相反的意思，这给我们记单词带来了很大便利。然而，也有一些词语加了这些通常表示反义的前缀之后没有改变原意，这反而容易造成记忆混淆。我们不妨一起来整理一下吧，把这些例外的单词搜罗出来，专门记住这些“另类”的词。我这里先列出一些，这些都是GRE红宝书里的：

flammable 易燃的----inflammable 易燃的
passion 激情----impassioned 激情的
passive 被动的----impassive 冷漠的，无动于衷的
valuable 价值大的----invaluable 价值连城的，极宝贵的
loose 松开----unloose 松开
soluble 可溶解的----dissoluble 可溶解的
solve 溶解----dissolve 溶解
personate 扮演----impersonate 扮演
fury, furious 狂怒----infuriate 激怒
pulse 脉冲----impulse 脉冲，刺激
sever 切断----dissever 切断
habit 居住于----inhabit 居住于
cense 焚香，用香薰----incense 香味，用香薰，激怒
rip 撕开----unrip 撕开
coming 来到----incoming 来到
famous 著名的----infamous 臭名昭著的（仍然是著名，只是贬义）
ravel 纠缠，拆开----unravel 拆开

ravel是最最最最另类的词，这个词有两个截然相反的意思：1.缠绕，纠结，2.拆开，拆散，自己跟自己竟然是反义词！连红宝书上对ravel的英文解释就是unravel，我滴神啊。

有意思。
关于ravel和unravel，Quora上的一个回答不错

First note that no one uses the word "ravel" these days (except maybe in knitting or something), but "unravel" is common.  Anything that is metaphorically a "fabric" can unravel -- a relationship, for example, or a story that turns out to be a lie, especially if it happens gradually, like a sweater that starts to unwind as you pull on the yarn.

A "ravel" (noun) is a loose thread that has "raveled out" (verb).  I had to look it up.

Maybe it's like the word "unroll."  When you unroll a rug, you also "roll it out."  The word "roll" refers to a shape more than the action, so the action is implied by surrounding affixes and particles.  Perhaps it is similar with "ravel," which just describes the situation of there being a loose thread.
