You can unleash havoc. Not sure what you're talking about silly blondie. ;oP

true, but there's only a few usages. wreak is singular i think

it's a verb... can't be singular or plural

singular in its usage i mean. it's only ever used in combination with one other word

it definitely isn't *exclusively* singular. and it's pretty safe to say that "wrought havoc" or "wreak[ed] havoc" is a snatch from some literary prose i'm unaware of and people just used that way ...

are you talking about wreak or havoc?

lol, i'm talking about the words being exclusively bound.

in the end, i don't find either of them weird. i like 'em both. together and apart. useless info: as a lame teen, in the early days of aol... for a long time my screen name was Amok Havoc. ...

that's actually a perfect example, it's exclusively bound to the word "run" omg they've run amok!
