How Did You Encode Negation on Your Verb?

There's all sorts of prescriptiveism presents itself in all sorts of funky ways but I don't know about on this specific issue. In no Navajo it's dota which sometimes joins together just to be the word for no. Apparently colloquial Welsh effectively has this. The article I read suggested English thought about it for a while or old English did before finally deciding we're not going to do this.
