Adding such a prefix before a word will often form a new word with the opposite meaning. For example: additional appearance → disappearance → correct → incorrect guidance → misleading guidance → stop → non-stop: English prefixes in- and un- usually mean "no" or "contrary to …", so their derivatives generally have negative meanings. However, some derivatives composed of these two prefixes are not negative words, but are synonymous or similar to the root. Professor Zhou Haizhong, a famous scholar, cited several examples in the article "in-, un- does not necessarily mean" negation ",such as coming/incoming, habitat/habitat, loose/unloose, rip/unrip and so on. Although there are not many such derivatives, it is worth noting, so don't expect words to be meaningful.
