Meanings of っこなし


**How many meanings does っこなし have?**

On the one hand, I've seen in jisho and
[here](https://japanese.stackexchange.com/questions/6836/what-
does-%E9%80%83%E3%81%92%E3%81%A3%E3%81%93%E3%81%AA%E3%81%97%E3%81%AB%E3%81%97%E3%82%88%E3%81%86-mean)
that っこなし is a variant of っこない, which means "no chance of; no way that;
certainly not; will never happen".

However, the usages I've found for っこなし seem to differ in meaning.

In these sentences:

> そんなつらいこと言っこなし。  
>  固いこと言いっこなし。  
>  細かいことは言いっこなしだよ。

**Would っこなし have the function/meaning of an negative imperative (Don't say
...)?**

And in this sentence:

> 誰が勝っても、恨みっこなしね。

I know by jisho that 恨みっこなし means "with no hard feelings", but **if translated
literally, what would っこなし mean here?**

**Besides, is there another case where っこなし would have another different
meaning** apart from 1) "no chance of; no way that; certainly not; will never
happen", 2) "Don't ..." (negative imperative) and 3) 恨みっこなし?




In English, "No smoking" is grammatically not an imperative, but it
effectively has such a meaning ("Don't smoke").

Likewise, ～なし is grammatically not an imperative (it's just "No ～"), but
depending on the context, it can be interpreted as a (negative) imperative
("Don't ～"). Although っこ and なし are often paired together, なし by itself can
effectively mean "Don't".

  * それ以上はなしだ。 No more. / Don't ask more.
  * 反論はナシですよ。 No rebuttals please. / Don't argue back.

Besides, ～っこなし is not necessarily a negative imperative, either. For example,
勝てっこなしだよ means "There is no chance of winning" rather than "Let's not win".
