[Vocabulary] I want to know about prefixes which infuse “negative” meaning.

[neincredits]

There are negative prefixes which add negative meaning to words: un-,in-,a-,an-,counter-, and etc.
What I am wondering is if there are rules for combining these prefixes with other words.

For example, “in-“ and “un-“ have same characteristic, which add negative meaning to words.
We use the word “unhappy”, but not “inhappy” or “antihappy”.

If someone knows about it, I’d be really happy. Thanks!

Welcome to the forum. :hi:

Your sentence above doesn't make sense. You've used "unhappy" twice.

Oh, I didn’t notice it! I made a correction about it.

You shouldn't change the original post, neincredits, because the following response (emsr2d2's in this case) sometimes doesn't make sense if you do that.
I think you can type in the reason for an edit, such as "Fixing a typo".

It makes me think about one characteristic of language : customary. Thank you for your nice explantation! I’ll bear that in mind for later studying.
