Sometimes a phrase just strikes me as mysterious and this is the one for today: plenty well enough. It's got to be colloquial, right? Like "anyways" and "anymore" and "down cellar"? But from what region?
The line I was using was "I know him plenty well enough" and after I wrote it, I wondered -- southern? New England? Rural upstate New York? Unfortunately, google hasn't helped me out. I might be the first person to have written this question on the internet, which actually would be kind of cool. I like the idea of wondering something that no one else has wondered. But that still leaves me wondering.
