Question

I'm looking for a word that means something has both positive and negative aspects attributed to it.

Answer 1

A swear word, such as fu*k. It is positive because it refers to reproduction, family, children, and pleasure. On the other hand, it is negative because it is a swear word that is extremely degrading.

Answer 2

I don't think he's asking for an example of such a word; I think he's asking what the word is that describes such a word.

If such is the case, BHudson, then you may be looking for "ambiguous" or "double entendre".
